slang for Jehova's Witnesses.  Due to the fact that they come knocking on your door almost every damn saturday morning when ur trying to watch cartoons or eat breakfast.  They feel compelled to interrupt your important free weekend morning by telling you about how god loves you and such.
I was beating off to some ill ass porn, then the knock-knocks came callin and I had to put the beef away.  I got pissed, drew a pentagram on my forehead and answered with a massive boner, informing them that I had found solice in satan and blasphemy.  I asked them if I could get back to having sex with this downs syndrome girl I had picked up at the bus stop.  They haven't been back since.
