Years ago I had a "friend" at the poker tables (in quotes because friend or no, you're trying to clean each other's clocks) and whenever one of us beat the other in a big pot the loser would text "ymscih" which is a line from The Exorcist (Your mother sucks cocks in hell). Happy days Great film.

"Jaws" is pretty much a perfect film.

"The Vanishing" (1988) "Spoorloos" is shocking; if you've not seen it, see it without knowing anything about it. Septics remade it and ruined it.
