ultra shit

The moment while in school and you get a pain in your anus causing you to ask to go to the bathroom. When you stand your ass contracts causing you to make a rock solid projectile to launch out of your ass following a tsunami of loose shit killing everyone behind you.

Steve:"Dang dude I just took an ultra shit in class today, killing my teacher!"
Josh:"Whats an ultra shit?"

Ultimus Asteri

Ultimus Asteri is a ROBLOX clan created by user Xransot, and co-owned by TotallyMainTrynda (goes by "Color") and CrypticDIO (Goes by Syther). They're themed around PVP and have over 300 members. They claim to be the best, considering you can only be accepted or invited into UA through your skill and intelligence. This is ironic, considering Syther is a bum.

This guy who's a god at Arsenal joined my game and then said that I should join Ultimus Asteri. Literally, everybody in this discord server is a god at Arsenal.
