Some people say "that's gay" or "you're gay" as an insult to heterosexual people or other events. If you are one of those people, brace yourself, you're in for a shock.

"Gay" isn't a synonym to: stupid, weird, uncool, wrong, sucks, stinks, or any other insult like that.

Saying "that's gay" is basically saying "Look at me! I'm ignorant, insensitive and close-minded!"

The same goes for "retarded"
Guy 1: "My parents grounded me. Ugh"
Guy 2: "Man! That's gayyyyy!"
Girl: "Idiots."
