FSMSpeed

"Flying Spaghetti Monster Speed". A nondenominational farewell, used in place of saying "Godspeed." It carries the same sentiment of wishing good luck but without endorsing a specific creator, instead substituting the "Flying Spaghetti Monster" deity popularized by atheists combating Intelligent Design.

FSU

Fuck shit up.

Stealing traffic/construction cones, chasing small child men, yelling "don't fuck with my friends" at innocent passersby, sleeping in garages just because, skinny dipping with sexy Scottish men, having wrestling matches on the floor at 3 a.m. to prevent the bar from closing, taking a shot of tequila whiskey baileys and malibu just for fun, streaking in front of small children, and most important snuggling.

Sooo what are you and the rest of the dream team doing tonight??

Oh I dunno, I suppose we'll just FSU. The usual. You?

Probably just watching you, wishing I was half as cool.
