From Mario Kart, a Nintendo game.

Whenever you get ahead and think you have it made, someone behind you shoots a blue shell at you and takes you out.

(Blue shells fly directly to the person in first place and pack the biggest punch in the game)

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.
