There was a cartoon that used to run in my college newspaper (drawn by a student). One "episode" dealt with the rampant proliferation of acronyms on campus, which had pretty much reached the level of being a separate language. Anyway, the protagonist character went into an acronym-hallucination and was found crouched on the floor of the laundry room by another student, who asked, "RUOK?", to which he replied, "FU".
