Janitor

[Dave Paprocki]

When two people are fighting in a FPS or any type of shooting game and a third person comes in to kill that last man standing with low health. (cleans up the mess)

[Julene]

A Janitor is the kinda guy who pulls girls so hard, that he practically cleans up all the available girls, leaving none for anyone else.

[Rihanna]

n): A guy that hooks up late in the night at a bar or a party, by sweeping up the leftover drunk chicks. It generally refers to hooking up with riffraff, but can be used as a shrewd tactic if played with the right timing.
v): The act of playing janitor.

[Dianne]

To be a hypocritical [fascist] thug controlling every aspect of his [citizens] lives and [banning] those he dislikes for no given reason. An asshole of the highest order and a really boring idiot in terms of discussion.

[Monty]

A caretaker or doorkeeper of a building.
