The alternate name for that over-hyped, material stealing, asswipe of a comedian.
Guy watching Comedy Central:
Hey, wait a second! I saw Dane Crook use that same joke!
The act of getting a tactical nuke (25 kills w/out dying) in Call of Duty: Modern Warfare 2 using only the tactical knife attachment. NO KILLSTREAK REWARDS (besides the nuke)
25 tactical knife kills + no deaths = Tactical Knuke = EPIC WIN
As seen on the "Kill 'em All" youtube MW2 challenge.
