When a song is screwed, that means it's slowed down a bit. "Chopping" is when you have the record on one turntable, and the same record on another turntable but delayed one beat, then you crossfade between the two for a beat to double up a half-second part. Usually you "chop" on the fourth beat to double up the first beat of the next measure. DJs often use the "flanger" effect on one of the records to make the chops "swoop."
