noun. A real clustersmurf, I reckon (though less blue, in all senses).
Real citation: "Speaking of Collins, what's up with Jeff Fisher basically calling Billy Volek a liar yesterday? I still haven't figured out the whole Titans cluster-naughty word when it comes to how they went from Steve McNair to Billy Volek to Volek/Vince Young to Collins/Young."

Made-up citation: "Kindergarteners! What is up with the cluster-naughty word around the gerbil cage? Give that rodent some space, you little mother-firetruckers."
