An urkel is a percocet, which is a prescription pail killer. URKEL POWER is a term used to describe the feeling of being high off of a percocet. Just like the character Steve Urkel from the show Famiy Matters acts hyper, urkel power is the energy you get from a percocet.
Let's go get some urkel power! Or once the high kicks in, you simply yell "UR-KEL POW-ER!" and you have to do it in 4 syllables.
