look up any word, like thot:
 
1.
(Noun) A cock related object descending from the lebaneese tribe of lebanon. Lebs are often sucked in these tribes in exchange for cocaine and other sexual favors.
A lebisin (leb) can most commonly be found in your ears, mouth and other orifices. It is a universal term, often over powering the more common word, cock. Ex. Guy 1: "How many lebs have you sucked today man?" Guy 2: "Oh about 947,632." Guy 1: "O fuck man. Did u bap them all with a towel rack too?"
