"Gay Much" is used in everyday conversations to state that somebody is acting very 'gay
'. It is also to suggest that one (persumably a male) likes to become aroused around other guys. Often can be used in threatening situations where a person find themselves proned to attack from say a rapist
or cock hunter
1. You are with a group of mates and suddenly you see a male checking out another male, you then say gay much.
2. A gay man
starts wandering towards you, he then says come here little boy. You then say 'Gay Much', this will in turn cause the attacker to become confused and weak, he will start foaming around the mouth
, then will collapse on the ground and die.
