gay smile 

An open-mouthed smile intended to show off pearly-white perfect teeth. A way of showing how fabulous you are and what a fabulous time you are having surrounded by fabulous people and fabulous things.

You gotta love that Andy Cohen gay smile.

Gay silence 

When people start talking about straight stuff and you’re totally gay but no one knows it even though you’d think it’d be pretty obvious by now so you’re just sitting there like yeah cool guys—it’s like an inside joke with yourself.

Practically invented by Jodie Foster

“What kind of fella would you like?”

The gay is SILENT 

A statement made when someone or something is so obviously gay that it goes without saying. Often used when replying to someone whose gaydar is malfunctioning.

1:
Mark: My gaydar isn't working today. Is Rick gay?
Steve: Oh my god, girl, the gay is SILENT!

2:
Al: I'm in the mood for some gay music. Got any Erasure?
Scott: You think Erasure is gay music?
Al: Duh, the gay is SILENT!
