When you and your girlfriend cosplay as astronauts; she proceeds to paint your penis like a rocket ship before you bone her down.
Peter: "One small step for man; one big step for 'Astro Man'!"
Henry: "Peter; why are you screaming that off of our roof top?"

Astronomical fail. Something going so wrong as to require an extra adjective (astronomical) to accurately describe how terribly awful something went. Can also be used to describe a person who fails at something or just life in general.
"Dude, that part last night was an astro fail."
"You clearly can't dance. Astro fail."
"You are such an astro fail sometimes."
"You clearly can't dance. Astro fail."
"You are such an astro fail sometimes."

Completely underrated. Astro turf should be used to pave driveways and should replace sidewalks, as well as everyones lawn. It should be used for clothes and curtains. Everything should be covered in it.

What the media did with the Houston Astros is a lot like people being told an athlete should be their role model. The media doesnt need to tell somebody which teams to like and which ones to hate, any more than they need to tell somebody who should be their role model, rather than choose one for themselves.
There's nothing worse than a fan that hates the Houston Astros because everyone hates the Astros, or because the media says they're cheaters, wife beaters, criminals, and degenerates, and not for their own reasons.

A date, in which two people pretend to go for a 'walk' but actually end up fucking their brains out behind the newly built sporting facility.
Girl one: Oh yeah, me and him went for an astro turf the other night, it was amazing.
Girl two: I wish he'd taken me for an astro turf...
