An item used to clean up after "wacking off". Items can include but are not limited to napkins, paper towels, hand towels, socks, T-shirts, random scraps of junk mail, your underwear, your partners underwear, couch cushions, and your Halloween costume from 2 years ago.
I didn't plan ahead before I started wacking off, so I had to use my shirt as a wapkin to clean up after I finished.
I hate dudes who don't have trash cans in their fucking bathrooms in their apartments. What am i supposed to do? Wander around with a bloody tampon in my bag? WAPLT
