back up peen

the term backup peen derives from that random guy jacking off in the back of porno flicks. He's just standing there and isnt actually involved and has no input. This term is used to describe a person who has no input and is just hanging out doing nothing and is just following someone else or it can be someone on tv whos in the background and isnt involved, same thing.

"Yo when i was gonna get in a fight with BJ he had his little sidekick Frank standing next to him doing nothing, he thought he was so tough." " Yea man, god damn backup peen"

Back up singer complex

When an aspiring singer never makes it as a big star, they move forward in their life making sure they're always in the spotlight; even if it means making people feel bad about themselves.

I don't know why my man's mom is always trying to compete. Always trying to be in the spotlight, like she got back up singer complex or something.

Beep when you back up

When a person accidentally puts their foot in their mouth or otherwise insults someone, or makes everyone aware of an elephant in the room. Then he or she tries overly hard to make the situation better, or cover up their tracks. Like heavy machinery moving backwards, it's definitely noticable.....

"Wow, you really pissed off Cassidy, do you always Beep when you back up?"
