A term for Justin Bieber who sounds like a pussy so thats where the beaver comes from. If it wasn't for him I would listen to the radio. So i am stuck with youtube. Beyonce has deeper voice than him, his cherry probably hasn't been pooped either. This word can describe ANY kids like.
Girl: OMG I love justin Bieber!!!

Guy: Are you a lesbian because he is really Justin Beaver. So he has a vagina.

Girl: But i love his voice!

Guy: He sounds like a 2 year old girl on helium.
