A question heard on fourth grade playgrounds, where the worst possible insult is to insinuate that someone is gay. Compare to Have you stopped beating your wife?, which is similar except that falls apart if you aren't married.

A kid would ask "Have told your parents you're gay yet?"
An answer of yes or no will insinuate that you are gay.
