A challenge to fight. Mexican slang. When one Mexican mad dogs another Mexican, it is the usual reply. Directly meaning "what the fuck you trippen on, asshole?" Or "what the fuck is your trip asshole?" A usual reply when a stranger get's involved in another's arguement. A reply when a stranger gives another a dirty look.
