Surely not a word. If so, then it's a verb meaning "to make syncopation", to create rhythmic forward motion via accented off-beats. Quincy Jones would say that this is the biggest change in pop music since he began working the milieu - the mainstream advents of funk and world musics have made syncopation common. But as someone who still has "Get away from my drums!" ringing in his ears, why name me "Syncopated Smurf"? At least the drum machines didn't yell.
