At Mark Zuckerberg's school I remember a story about him getting in trouble for PHP. The school had a zero tolerance drug policy and PHP was confused with PCP.
In reverse, I wonder how well known Irish and British slang is in the USA: “Bumming” can mean to obtain or make use of something that belongs to someone else by begging; “fag” can mean cigarette; “for the craic” (“craic” pronounced “crack”) is “for fun”.
(And thanks to the very early part of my mother’s Alzheimer’s, I also know that an archaic meaning of “glory hole” is a cupboard for miscellaneous items, and the etymology of the sexual reference is that both are where you put your “junk”).
