Vitriolic Best Buds/Web Original

Examples of in  works include:

"She may be a pain in the ass, okay? But she's my pain in the ass."
 * Policeman vs. Fireman on Youtube has the ongoing "friendship" between Butt Monkey Policeman Perry and chick magnet Fireman Jake as the main subject matter. Hilarity Ensues.
 * The Jake & Amir sketches from College Humor are built on this trope. Amir is usually the one who is annoying (and often stalking) Jake. However, they occasionally switch roles.
 * The Tipping Forties crew are a circle of jerks but have been friends for a good time. See their Mario Party LP.
 * The Switcher's Two Best Friends Play series (viewable here). Only genuinely good friends could hate each other that much.
 * The Wisenheimer's Podcast between Yotam Perel (Lazymuffin) and Max Gilardi (hotdiggedydemon) thrives on this trope.
 * Voldemort and Quirrel from A Very Potter Musical. Harry and Ron also tend to act this way toward Hermione, but  Harry considers her to be like a sister. Ron also fits with his little sister, Ginny. To Draco:


 * Trixie and Jack of Black Jack Justice fit the bill. Not an episode goes by where the two PI's don't bicker and threaten each other at a pace that would make the Gilmore Girls jealous. They even have some pat, oft-repeated gibes for when they're tired ("You miss me?" "With every bullet so far" is pretty common). Police Lt Victor Sabien fits this bill with both of them. In fact, when an episode opens with Vic walking in and not insulting them, that's their first, best clue that he's truly upset.
 * For that matter, Jack and Freddie the Finger have a relationship of this sort, but a little softer and more gentle than the rest of the cast.
 * Lewis and Simon from the Yogscast, especially in the Minecraft series where they're regularly hitting one another with diamond swords, pushing each other off blocks, and being generally snarky... And the rest of the time they're calling each other pal, helping each other through fear inducing challenges, and making Slash Fic jokes. Woe betide anyone who unites them against a common enemy.
 * The title characters of Xolga and Mr. Toko practically are this trope. Every time Mr. Toko wants to help Xolga in some way, Xolga being his Jerkass Woobie self, constantly insults Mr. Toko and most of the time doesn't take him seriously. But despite their differences, they seem to really care for each other.
