A booster is an individual you look at and wonder how they get through every single day. A person riding a bicycle through life in the wrong direction. Even going in the wrong direction, they constantly hit the curb, landing on the bike frame, over time their ball nuts are transformed into a mangina.
A true booster constantly has something to say and wants to help with everything and anything that involves the opposite of their actual responsibilities and will wear themselves out trying to boost out of those responsibilities. A booster is a lifetime member of the “get a long gang”. The “get a long gang” roams through life on a single red caboose bringing eye rolls and temple rubs to all they encounter.

Coworker: Hey guys what happened to the slide show I made that we are suppose to present in 10 minutes?
Coworker 2: Ummm, that booster Messica thought she had to make a new one and shredded yours. She also left you a note that she had to go to an appointment for going blind, something about closing her eyes and it getting really dark. She gets better when she opens them.

When a rapper or hip hop producer samples or loops an older track. This is known as "Boosting a track." This may also refer to when another beat is played over a vocal track in a club.
The beat on Notorious B.I.G.'s "Juicy" was "boosted" from a classic R&B track.
