A similar idea to a Peurto Rican
Shower, originally coined on the show Happy Endings, s2e16. A
Whore's Bath is when you, instead of showering, rub dryer sheets on your armpits and splash
water on your genitals in a lame attempt at keeping some sort of society-accepted level of hygiene and cleanliness. This usually occurs after a one night stand.
Person 1: Hey, you look
pretty disgusting.
Person 2: Yeah, I know, I hooked up with some
sketchy guy last night and took a
Whore's Bath in the bathroom.
