Rost Boeuf

Slang for happy drugs like ecstasy or mdma that are tremendously good fun, when used in the correct environs, such as a large German techno rave dungeon, or oubliette.

"Would you care for some rost boeuf, monsieur? I put it to you, sir, that you are not raving hard enough, at least, not to the standard to which I, after three morsels of this extraordinary narcotic, have become accustomed to."

ROST

Also known as STINKY, QUEER BOY, FAT FUCK or RAT FUCK. A "ROST" can be observed usually with grey, unbrushed teeth, no deodorant, and wearing the same sweat pants for months on end. Known to mate with the JERASSICA species, the mating rituals include things like bacon grease, butt crack lint, fish vag, wet queefs, and vomit.
