"That's so gay" is not OK.
Hilary Duff, Wanda Sykes and others are part of ThinkB4YouSpeak, a new campaign from the Gay, Lesbian and Straight Education Network designed to discourage use of the phrase that's so gay as an all-purpose putdown or expression of teenage ennui.
See Duff in the act above, or go the website to check out more videos that work in the classic PSA mode: A celebrity springs on some fool who desperately need some educating. Enlightenment ensues.
We welcome the videos and the sentiment behind them, and just wish more celebrities were lurking in the shadows ready to school some chump the next time it's needed.
Until then, it's up to you.
