Covid pee stain
A Covid pee stain is when you go to hit the hand sanitizer pump and because it has crud buildup in the nozzle, rather than shooting in your hand it sends a spurt of sanitizer at 200 mph that nails your pants in the crotch and thus produces a covid pee stain
I’m never using hand sanitizer at the gym again after giving my light grey sweatpants a Covid pee stain.
