Top Definition
Knowrighticide is the homicide of a person who uses the phrase, "I know, right?"

It can describe what might amount to a cultural act or an offence defined by the victim's fuckheadedness. Often it is the mother who commits the act, but criminology recognizes various forms of non-maternal knowrighticide.
Perp: Nice weather we've been having..

Victim: I know, right?

Perp: FUCKING DIE! *stabby-mcstab-stab* #knowrighticide
