Astro Blasto 

Comes from an episode of 'That's So Raven' in which Devon (pronounced deh-vawn) is obsessed with some sci-fi TV show, much like Star Wars, only, no Leia in the metal bikini.

Devon: Astro Blasto!
Imaginary White Guy: Shut the fuck up.

Astro Blasters 

A game in which only boys can play. Two or more boys jerk off and the first to ejaculate is the winner. A popular game among Football players. You always wondered about the star football player, well you didn't know he was also an Astro Blasting champ too, did you?

On the way back from an away football game, four of the guys played Astro Blasters in the back of the bus. Go figure, Chris would win.

Astroblast 

The act of washing ones rear end after quite the nasty poop, in the shower.

I had quite a bad sh*t earlier, so I astroblasted your shower. Sorry for the smell.
