Batman Beyond/Radar

"Nash: I'm sick of the mall. Let's go for a ride.
 * For starters, take a look at this dark and sexy intro and tell me this passes for a kid's cartoon today.
 * In "Golem":

Blade: You like that car more than me.

Nash: Who's talking about cars?"

"(Terry and Dana are dancing together and are about to kiss, when she suddenly backs up) Dana: "Oh, no..." Terry: "Sorry!"
 * This one was actually blatant enough that the Hub Channel caught it and edited it out.
 * This little gem from the same episode:

Dana: No, look! (points to a fellow student arriving soaking wet)"

"Chelsea: (knowingly) You've never wrestled with him."
 * Or in the very first episode...

"Terry: An invisible boy in the girls' shower... why didn't I think of that? Dana: What? Terry: Uh, nothing!"
 * The episode "Eggbaby": At the end, where the teacher quips, "Who knew that [Terry] would make such good father material?" the look Dana shoots him suggested more baby making than baby raising.
 * The look Terry makes in response solidifies this. You can hear him mentally screaming "Oh jeez she wants a baby..."
 * A great one in "Revenant":

"Sam: "...I just can't relax knowing Cuvier and his guinea pigs are out there doing God know what!" Barbara (grinning): "I bet I could relax you!""
 * To those who don't get the joke here; Terry's Batman suit has a cloaking device.
 * In the episode "Disappearing Inque", the shapeshifting villain Inque has promised a reward to Aaron, the lonely security guard who freed her from prison (voiced by William H. Macy). After they steal some mutagen Inque needs to restore her full powers, Aaron reminds Inque of the promised reward. Before he can voice his request (it turns out to be a dose of said mutagen), Inque proceeds to ooze out of her clothes and asks, "Here? Now?"
 * Also, when Aaron and Inque are in his apartment, Aaron comments on how it'll be hours before it's dark enough for her to go outside, to which Inque responds with "well, maybe we'll think of something to keep us "busy" until then" and she says it in a rather "sexual" tone.
 * In the episode "Hooked Up", a groupie asks a rock star for his autograph; as she tells him, "You can sign me anywhere you want," she begins to lift up her shirt.
 * There's a particularly vague one in "Dead Man's Hand", during the Cold Open when the Royal Flush Gang robs the yacht. Ten snatches a necklace from a blonde, claiming "you'll get a new one soon enough" and Jack says "she earns hers the old-fashioned way".
 * He was probably just implying she was a gold-digger.
 * I thought so too, and that works even better, implying that whoever she's with is her sugar daddy.
 * How about the Sexy Discretion Shot in "Once Burned" that fades to black with Terry and Melanie making out on his bed and then cuts back in several hours later? Does anyone really think they were just talking until sundown?
 * In Splicers we see several people injected with the spilcer juice. Even without needles, it's very clear that the tubes were syringes-you get to see the liquid inside go down once they hit the skin. We even see Terry injected against his will and Cuvier essentially overdose.
 * Now that is probably the best "don't to drugs" episode ever Splicing has all the hallmarks: Altered behavior (increased agression, Decrease in thought process the more you take), An odd dependency by the Ram-Guy, Hustling "norms" to do it, Debates over legality that involve "impartial tests" and the justification to by Dana which took the cake: "The law's against everything we're into." now, doesn't that sound like most teens justifying doing drugs (among the other things teens often do)?
 * "Hooked Up" has an even more blatant "Don't do drugs" allegory(heck the title itself is slang for doing drugs) in this case it's a virtual reality simulator that lets people live their ultimate fantasies like being a rock star, the trademarks include:severe withdrawl for anyone who leaves the VR, people willing to resort to stealing to get enough units to pay for more VR time, violent irrational behavior, using VR to escape reality because it makes them happier(many an addicts justification for doing drugs).
 * And another on the risque front, courtesy of Barbara Gordon:

"Waller: Bruce's DNA was easy enough to obtain: he left it all over town. (cut to Terry giving Waller an awkward stare.) Waller: Not remotely what I meant."
 * There's a scene in "Epilogue" where Waller tries to explain that she obtained Batman's DNA (for one of her late genetics experiments) from blood he left at the scene of a fight. Judging by her face, you almost get the feeling she phrased it like this on purpose:

"Chelsea: He can haunt my castle anytime!"
 * How about the pleasure causing tuning fork from "Babel"? Those were some pretty blantant sex noises.
 * The premise of the illegal Sex Bot episode alone may qualify for this, but there's also the bit where Howard takes Cythia up to his bedroom during his party and is asked "So are you two going to the private party?"
 * In "Revenant" when the students are wondering if deceased student Garrison Jacobs is behind unexplained events, the girls all remark on how goregous he is, especially Chelsea:
