When the whumpee is someone who needs their hands for what they do (i.e. they're the team's resident lock picker or something you need dexterous fingers for), and the whumper goes to work on their hands. Broken fingers, punctured nail beds, burnt finger pads, anything that is painful but will also keep the whumpee from doing their job for a while and act as reminders of what was done to them.
Brilliant!
