1. A delightful term first coined by my brother Luke specifically referring to HALO. To PwnSwrd is to pick up the energy sword and proceed to annihilate the oppossing n00bs with gusto. PwnSwrd ing must include multiple kill streaks, embarassing from behind slices or levitating slices when the trigger hair turns red in mid-jump.
2. This term can also be applied in Call of Duty 4 to mean shooting an enemy at point blank range, making it seem that your ak-47 is the feared ak-50 (a Kalishnikov with a bayonet attached).
3. Basically killing multiple n00bs with melee attacks rather than gunfire
"O man what nerd fags! I just PwnSwrd their entire team!
