Vitriolic Best Buds/Web Animation

Examples of in  include: "Church: You're not Caboose's best friend, okay? You don't have a best friend. You know why? You don't need one. You're Church! Knowing other people just waters down the experience. Live the dream, buddy!"
 * Red vs. Blue: Church and Tucker. Actually most of the friendships in the series seem to work like that... not surprising, as in Real Life the creators and voice actors seem to get on this way.
 * When Caboose comes to his new base in Reconstruction, he tries to literally snipe him, but his aim is so bad that he repeatedly missed.
 * Church is still clearly devastated when  though.
 * This comes up when Church meets the version of himself inside of Caboose's head. Mental Church claims to be Caboose's best friend. Real Church is not amused.

"Strong Bad: I thought we were bros! Homestar: Wait, I thought I thought we were bros, and you're always beating various stuffings out of me."
 * Simmons and Grif also qualify quite nicely for this trope, even though always throwing insults or worse at each other they never stop being Those Two Guys (if not Heterosexual Life Partners). In fact, the very first scene of the series set them up to have this kind of friendship.
 * The voice actors for Simmons(Gus) and Grif(Geoff) also qualify, they make fun of each other for their heavy drinking, lousy gaming ability, extreme nerdiness, etc. but they also lived together for years, have made out with each other (as a joke), and live a block down the street from each other to this day.
 * Doc also seems to think that he and O'Malley have this relationship by season 4. However, given that O'Malley is pure evil, his hatred for Doc is probably completely genuine.
 * Vendetta hates Charlotte in Making Fiends, often attempting to kill her with her fiends. However, Charlotte (being a Cloudcuckoolander Genki Girl) thinks they're the best of friends.
 * Homestar Runner and Strong Bad. (Though Strong Bad is occasionally almost decent to Homestar, Homestar is oblivious to Strong Bad's constant insults almost all of the time.) This is noted a few times in Strong Bads Cool Game for Attractive People:

"Coach Z: Aw, Bubs loves me like a brother. (Beat) Hates me like a brother, too!"
 * Meanwhile, Bubs and Coach Z describe the second type.
