A guy who tells girls that they are beliebers just so they can get laid. They've usually done a lot of research so that they're ready to hold out through an everlasting and stupid discussion about how hot Justin Bieber is.
Belieber: OMG!!!!111 Justin Bieber is so damn hot!<333
Boybelieber: I totally agree! That kid has so much talent!
Belieber: :D <3 Want to have sex?
Boybelieber: Sure!
Boybelieber (to himself):Gotcha!
A girl who lives and breathes for her boobies. Its the focal point of her existence and shes very proud of it, in a sick way. Could also be referring to a girl whos boobs are huge because they're generally chunky.

I asked the bongelier if they sold bongs, and he was like, "Nah, dude, but I can totally show you our complete line of waterpipes - we have some kick-ass new ones with cool diffusers - totally appropriate for your, um, tobacco."
