if i had to pick a dude

This phrase is rather uncommonly used. Males use this as a "no homo" kind of thing when told odd questions like "if you were gay who would you date?".

If I had to pick a dude?

Tuxedo Mask from Sailor Moon

Peter - If you were gay, who would you date?
Henri - If I had to pick a dude.... it would be Charles

Peter - Yo thanks man. I'd date myself too.
