1. v. when you are playing mario kart and some dick decides to send you a blue shell, which flies towards you and smashes you in a huge explosion. It is extremely frustrating.

2. v. to get fucked over, screwed over, stabbed in the back, owned, ect. However, do not use this meaning unless your friends play mario kart because people will not know what you are talking about and will probably think you're a nerd.
