An ugly female friend who viciously defends her other female friends from engaging in conversation with any male. Traditionally either man-hating gay or profoundly ugly; there appear to be no male triceratops. Attacking is always suicidal. The tactic is generally to lure the friends away from the triceratops nest so that you can talk to them without being impaled. See also cock block.
