A sniper rifle in the popular game, Call Of Duty Black Ops 2. It was ruined by David Vonderhaar on July the 23rd when he thought of getting rid of quickscoping, yet failed since it's David Vonderhaar.

Term for when an electronic music producer / or musician in general releases a tune on their own digital label that no-one buys, listens too or gives a s*** about just so they can say they have a release. This can be accidental if this only happens with one release. If however they release scores of tunes in this way they are clearly either:
(i) Trying to counterfeit reputation ie. trying to mislead people of their true standing in the game to get bookings / further releases
(ii) Trying to be counterfeit status among their contemporaries
