hemorrhoid tourniquet
Hemorrhoid tourniquet: trying on thong underwear and getting your hemorrhoids caught in the floss when you pull them off.
During some man-talk over beers, one of the guys explained how he tried on his girlfriend's thong during a hemorrhoid flare-up and it got really squeezed as he took them off. His beer buddy didn't miss a beat as he explained "No Pain, No Gain" and confirmed that hemorrhoid tourniquets like that were coming into vogue at old man frat parties.
