The act of getting an object shoved up your ass. Usually done when the victim is wearing some sort of pants, so it's not to be taken literally, unless it's dealing with sex (see anal).
This term was made famous by Daniel Tosh during an episode of Tosh.0 when he showed a video of Moammar Gadhafi get sodomized by some type of sword.

Guy 2: Totally Gadhafi'd her, bro.
Guy 3: Nice.
