LB 

This means to "Lick Balls" in whatever sense you can take it.

When speaking with someone in an angry or frustrated state, you can say "LB" instead of using profanity and you will get your point across.
Such as, "Why don't you just LB!"

LB 

The most white guy you know. Makes weird faces to you without noticing it. Is a king. Picks his nose sometimes. Everyone thinks he's an idol. Most likely will run around in the hallways like a sped. Probably plays lacrosse and wears vineyard vines.

Did you see LB picking his nose?

LB 

An endearing nickname that can be used for anyone with a name starting with the English letter “L”. The B stands for baby. Ex: Leslie Baby... This nickname is often recognized and misinterpreted by graduates of the early 2000s and mid and late 90s as the nickname “Little Bit” pronounced “LilBit”.

LB when are we gonna spend some time together?
