back up

When you drive your car in reverse, you back up.

That moron scratched his car when he backed it up.
You should use both side and rear mirrors when you back up your car.

Back2pray

This is a sexual act between four men in which one of the men strokes the scrotum of the other man. Meanwhile the man who's scrotum is being rubbed will be anally but-raped by the third man. Eventually the 4th man will receive the sperm nutrients that he needs to thrive.

The actual definition of this is the recollection of the act.

The Next Morning

Man One: Wow man! Last night was insane, wasn't it?

Man Two: What was? Back2pray?

backpacker

1. A person who travels independently, typically on a low budget, usually staying in hostels or with locals rather than in hotels. Usually aged between 18 and 30 but can be older. Backpackers often travel for several months at a time, and do not consider their trip to be a "holiday". Due to the fact that backpacking was popularized by the hippie movement in the 1960s, there is some association of backpackers with aspects of counterculture.

2. A fan of certain types of "alternative" hip-hop. When used as a derogatory term, it can imply that the individual is suburban/middle class and listens to "nerd rap" rather than "real rap". When used as a neutral term of description, it can imply that the individual listens to thought-provoking, original, intellectual hip-hop. The term is especially associated with fans of the record label Definitive Jux.

1. "Last night I went out for a spliff with a bunch of Australian backpackers I met in a club, they were pretty cool guys."

2. "Oh I'm not really into that whole artsy backpacker scene, I prefer straight-up rap music, stuff like 2Pac and N.W.A."

back-up, back-up prom date

This is basically someone that you know will say go with you to prom if you ask them. This has to be a person that you can relatively stand for a full night, or else can stand to stand next while taking pictures and then ditch him/her for the rest of the night and hang out with that person that you actually wanted to come with. This has to be a person that you know no one else will want to ask, so they are definately available.

Steve is my back-up, back-up prom date, so I know that I am guaranteed to be going with someone.
