A slang term for an Ultimate Frisbee, emerging from frat-boy college campuses around the United States. Frosses come in a variety of weights measured in grams and they are made with plastic. Not to be confused with the discus throw or disc golf.
Cam: Hey brah, wanna go to the quad after the frat party and toss the fross?
Mikey: I would man, gotta sober up first though.
Cam: Don't worry dude, it's a chillaxed game.
Mikey: Sweet, can we pass the hacky sack afterwards, and listen to some Mac Miller?
Cam: I prefer Dave Matthews.
Mike: As long as we're tossin the fross high in the clouds every little ting' is gonna be alright brah.

A term only posers who aren't really Ultimate players use to describe a frisbee or Ultimate frisbee. As really ultimate players know, only a disc is used, not a frisbee.
If someone uses the term "fross," flip him off and walk away, he is not worth your time. These type of posers generally throw some slanty pass that doesn't go anywhere near you and usually ends up closer to them.
Poser: "Hey brah, you wanna toss the fross? My new Wham-O frisbee just came in the mail"

Real Ultimate player: "Eat a dick."
