I Banged Your Mom

"Demetrius: Villain, what hast thou done? Aaron: That which thou canst not undo. Chiron: Thou hast undone our mother. Aaron: Villain, I have done thy mother."

- Titus Andronicus (theatre)

When the Hot Mom succumbs to the necessary implications. Basically this is when one character is sleeping with another's mom, usually for comedic effect.

Often carries the implication (if it's not stated outright) that the speaker was able to sleep with the mom because she Really Gets Around, usually prompting an angry My Girl Is Not a Slut reaction. Reactions are especially volatile if the mom has only recently become divorced/widowed from the dad, and especially if she's still married to him. The characters this is said to are usually male, and they almost never get similar remarks about their dads; possibly a result of Most Writers Are Male.

People seldom say "Thank you, man, she was so lonely after the divorce" or "I hope you had fun, and I'll kick your ass if she didn't" or "Well I hope you enjoy genital warts". Any of these would destroy the insulting intention with a good shrug-off. Strangely, often the only proof is the word of the person who says the line, and few of the attacked ever seem to seriously doubt the sentence. This trope is common mainly in American media, rarely seen (if at all) in continental European or Asian media (at least for comedic effect, it is seen for tragic effects in the form of rape, but then it's not this trope).

If it's just an insult - they never actually did it - check out Your Mom. "I banged your wife" is a variant, and much more insulting. If it happened a long time ago, see Luke, I Am Your Father.

 * Touched upon but never really gone into in much detail in Wicked Lovely: Aislinn's mother was previously thought to be the summer queen, prior to her suicide and Aislinn's reveal as said queen. This means that she had a relationship with Keenan. Whom Aisliin breifly falls in lust with in Fragile Eternity. It was non-sexual in both cases, but the Squick is still there.

("She wasn't young, but she was conscious.") Which becomes a list item later...resulting in a Shotgun Wedding. (Or, as Earl puts it, a "pistol pressed firmly to your temple" wedding.)

 * There was an old fiasco back at Deviant ART when the staff introduced a ridiculously flawed algorithm to sort popular deviations. Many members welcomed it, believing it will get the anime/fan art off the front page. Well the anime/fan art was instead replaced with a gif of a stick figure banging a "your mom" sign (that wasn't even made by the person who posted it).

Western Animation

 * Also, in "Chef's Salty Chocolate Balls", there is an all-new chocolatey treat called, "I Just Went and Fudged Your Mama".

Real Life

 * Your father, of course.
 * Averted if she used a sperm bank!
 * Can also be very easily averted if you aren't human. If your species reproduces through binary fusion, budding, sporogenesis, fragmentation, parthenogenesis, buckets, or external fertilization then your mom (if this term even makes biological sense) has technically never had sex.
 * In that case, what the devil are you doing on the internet?
 * Your mom.
 * Averted if you were adopted, so there's no evidence of that.
 * Not really. Someone had to have brought you into the world in a physical sense.
 * Do you know how difficult it is not to make this joke around your gf's children?
 * Yes. The look on your face would've been so sweet.
 * How about resisting the urge to say this in front of your ex-girlfriend's children and her husband?
 * A subversion, crossing over over with Your Mom: In an Australian Rules Football match between the St Kilda Saints and the Brisbane Lions, Brett Voss (playing for St Kilda) was lining up for a shot at goal when he heard someone call out "My old man fucked your mum!" He turned to see that the player who had said it was... his brother Michael, who played for the Lions.
