Gravatar 

A 2009 science fiction film by James Cameron featuring state-of-the-art CGI effects and widespread 3D theatrical release.

Jon: Hey have you seen Avatar yet?
Jim: What? Oh no, I heard that movie's pretty bad.
Jon: I thought you were seeing it last week!
Jim: No, of course not. We saw Gravatar. THAT movie was amazing.

Gravitar 

A water bong made of a 3 liter plastic bottle with it's top cut off and a 2 liter plastic bottle with the bottom cut off. The 2 liter bottle is has a hole drilled in the top that fits a bowl. Pack the bowl with weed and light then pull upward on the 2 liter bottle. Take cap off with bowl...put mouth by hole and push down on 2 liter bottle. Sit down and enjoy the buzz.

Holy shit I just took a hit off the Gravitar. I'm on cloud nine.

gravatron 

after you fuck a fat girl and she is laying in bed with you. The more she weighs, the more the bed sinks down on her side and the more gravity pulls you towards her. The force of gravity is directly proportional to the weight of the girl.

Last night Tom fucked a fat chick and when I looked in his room this morning the gravatron had sucked him in like a black hole.
