C-C-C-C-COMBO BREAKER

From The LURKMORE Wiki

A mild kind of thread hijack where a flood is interrupted by pictures relevant but inappropriate to the nature of the thread, usually to make fun of obsessive fans. A popular example is adding suggestive yaoi art to floods of cute girls, such as many Haruhi threads fall victim to. Original C-C-C-C-COMBO BREAKER is from the Arcade and SNES game Killer Instinct.
