Vitriolic Best Buds/Newspaper Comics

Examples of in  include:


 * Krazy Kat and Ignatz Mouse. Krazy loves Ignatz, Ignatz constantly insults/expresses his "hatred" for/tosses bricks at Krazy. However, Krazy loves getting hit with bricks...and Ignatz, for his part, genuinely cares about Krazy and spends a lot of his spare time dishing the dirt with the Kat (though it nearly always ends with the inevitable brick toss).
 * Nate, Teddy, and Francis from the newspaper comic, recently turned into a series of kid's books, Big Nate.
 * Calvin and Hobbes: The title protagonists, who even go to the point of violently beating each other up. This seems like a trend in Calvin's relationships, since he also has undeveloped Slap Slap Kiss with Susie.
 * Pearls Before Swine's Rat and Pig. Rat will abuse Pig to the point of literally throwing him under a bus, but underneath it all he does care for his little buddy, as evidenced by one strip where sat by an unconscious Pig's hospital bed.
