A Hot Chick Dump (HCD) is normal taken by a hot chick on vacation with her boyfriend at a public bathroom. Generally Hot Chicks give the impression that they do not defecate and therefore in order to keep this myth alive and not turn off their prospective spouse, they generally take their dumps in the hotel lobby bathrooms.
Dude in love. "I could swear that Susie just doesn't sh*t! She's incredible!"
Reality dude -"Bro, she's probably taking her Hot Chick Dump in the hotel lobby while you are at the bar."
