A smell given off by a particulary crappy and ugly drummer. Smells of roadkill, skidmarks, and hippies. Also faintly smells of cyanide. The smell cannot be stopped. The best course of action in this situation is to shag-ass outta where-ever the drummer is located. Drum Funk is also when a drummer is sucking of titanic proportions.
"The dudes drum funk was so bad, i had to dip away to keep from fainting!"
To come back to the place where you held your pre-funk or your final destination of the evening and attempt to revive the party by drinking the remainder of your booze (if there's any to be found). Very easy to do in a drunken stupor!
Sue: We should blow this joint and post-funk at my pad!
Lisa: But I'm already shit-faced!!
Sue: Fuck that! We're taking shots!
