The Gorilla is a mating technique developed by the drunk male. This strategy must be implemented from behind so that the female is completely unaware (otherwise known as the "sneak attack"). It involved a frankenstein-slash-zombie-like outreach of the arms over a female's shoulders followed by a sloppy and uncoordinated death grip around her neck/chest/anything in reach. The male then proceeds to try and dance with the female. Women who fall for the gorilla tactic either can't think or are painfully unstable.

An invisible entity, that, after a long night in a pub or a curry house, follows you home and while you're sleeping chucks your clothes round the room and shits in your mouth.

What you see when you are totally smoked out, usually indicating your limit.
