1) From South Park - created in an attempt to criticize the banning of kickoffs from South Park Elementary, Randy Marsh sarcastically suggests implementing a game called sarcastaball, in which the boys have to be nice to the opposing team instead of tackling them. The game is different from football in many other ways; its uniform consists of bras and tinfoil hats, and a balloon is used instead of a ball.
2) An overly sarcastic person.
1) OK, I think we should play sarcastaball.
2) Damn, this guy has been making too many sarcastaball comments!
