LBM 

LBM is an irritating Teenage Soap Opera. Constantly complaining about his/her/its tummy, and non-existant girl problems, you can find LBM in his/her/its natural habitat of Victoria Secret, sniffing the bras.

LBM: It involved hands under things...
STL:STFU LBM
Eric: We told you to stop giving guys hand jobs!

LBM is to annoying as Frogblast is to Halo tricking.

Littlebigman fails to go more than six sentences without saying the word 'girl'; its a proven fact. Littlebigman in himself is an oxymoron: he is big, yet little, and (heres the funny part) a man. He is not big, or little, he is pudgy. He is not a man, he is... we don't know what it is.

<Littlebigman> and then blah blah blah blah blah blah blah girl blah blah girl blah blah gay sex blah blah girl and gaysex blah blah.
