L.H.O.O.Q.

When these letters are read out in French it sounds like you're saying "elle a chaud au cul", which basically means "she has a hot ass".

Also the name of one of Marcel Duchamp's work, in which he doodled a stache on Mona Lisa.
Bro 1: Yo you see that girl at your 10 o'clock? L.H.O.O.Q. amirite?
Bro 2: Ya yeet.
Get the L.H.O.O.Q. mug.
