What one must say after punching someone in the back in Halo, generally followed by a quick session of teabagging.
It was 49-49 and I walked up to the laser tower, assassinated the guy charging his laser while exclaiming "assassinator", and teabagged him as the screen faded to black, giving us the victory.

See also assassin.

An organized game played mostly on college campuses in North America. It is usually run by and for students living in a particular dorm or group of dorms near one another. The game may last from a few days to a few weeks, and it ends either on a predetermined date or when only one participant is still "alive." (The person or people still alive at the end are the winners.)

Kills are made in different ways depending on the rules laid out at an initial meeting. For example, a bop with an empty soda bottle, a squirt from a squirt gun, or even a hug may be used to represent a kill. Often, each participant is assigned a particular person that they have to "assassinate" in each stage of the game as long as they remain alive. Lists of still-living participants are often posted daily in a dorm lobby or on an RA's door.

Assassins generally doesn't have any sort of safe bases or time-of-day restrictions on kills, so participants can be tricked or trapped into a "deadly" situation at any time or place, from a mid day English class to a drunken 3 am bathroom trip. It can cause some paranoia, but is generally regarded as an interesting way to spice up dorm life, meet new people, and get involved in some ridiculous scenarios.

Person 1 - What is assassination? Is it possible to assassinate yourself.

Person 2 - No.

Person 1 - Why?

Person 2 - Because that would be suicide and suicide is pre-mediated, not sudden. Assassins are prompted when there is something to gain. What would you gain if you killed yourself.

Person 1 - Nothing

Person 2 - Exactly

A large game played over an extended period of time, usually by 10 or more people, and typically set in a college dorm. Players are secretly assigned the name of another player to "assassinate," that is, squirt with a water gun when the target is not looking and when no one else may see the shot. When the target is assassinated, the assassin inherits the target of the deceased, thus closing the circle. The game continues until only one assassin remains.
Jan assassinated Meredith, then got Cindy since she was Meredith's target, and is now chasing Giacomo and running from Tyler. What a game!
