look up any word, like dirty sanchez:
Burger King Crown. Physically, it's the cardboard crowns you can get at the BK for kids.

Some gamers will wear their BKC whilst playing online in order to give themselves a psychological boost and therefore unfair advantage, much like a performance enhancing drug.

Used as an expression of winning. The guy wearing the crown is the king and current champion. Often this substituted for a championship belt for financial reasons.
I was playing BF Heroes yesterday and I won! BKC FTW!
