Astrobate 

It's when you place a plastic bag on you head and you masturbate and try to finish out before you pass out.

I was bored the other day and had some leftover Walmart bag so I astrobated.

Astroballs 

The ability to attempt things that are absolutely crazy and not feel fear; a pair of balls so big they orbit the Earth.

I can't believe you did that. Doing that required some fucking Astroballs.

AstroTatting 

The act of smoking marijuana, and then watching a muted version of the 2d Japanese "Astroboy" cartoon, while listening to the music of Ratatat simultaneously. The music and the cartoon eerily tend to sync up, no matter the start time of either.

Note- Most effective when performed as a night cap after a thorough night of drinking. In other words, a "passive" weed activity.

Dude, you guys were up laaaaate last night!

-Yeah, well we didn't get home til four and then we were AstroTatting for at least an hour.
