A phrase used to describe a boy who is a faggot to such an extent that he becomes incapable of growing into an adult, and will forever act like a toddler.
Signs of these people are evident when things like "People keep telling me to man up. Sometimes I don't wanna be a guy!" or "I'm such an emotionally sensitive person. I don't wanna be a man!" are spoken.
I always thought Billy was a faggot, but I think he's actually on the color spectrum.
