When someone is caught lurking and jerking they must make a timely getaway, thus resulting in an unfortunate jog and flog.
Phil: Why the hell are you all out of breath and sweating profusely?
Pat: just got caught doing a lurk and jerk at the mall.
Phil: that still doesn't explain why you're so sweaty...
Pat: mall security caught me behind the tanks at the pet store, so i had to pull a quick jog and flog all the way to the bus stop.
