what is with men using the term gay to explicitly express their opinion?

[Revytwohands360]

i say men because i rarely see women doing this also i am a guy. my friend does this i think it's idiotic. like for instance he says the game eternal sonata looks gay that's his reply that shows no intelligence but i'm not going to go on and on anyways has anybody noticed this and thought what the hell is wrong with this person.
