The website KidsInMind (which details everything that happens in movies so you can decide if its appropriate for your children) has released its guide for Deadpool, and rated the movie a solid 10 for profanity. Personally, I would have shot for a 12 but that's just me and I invent new dirty words all the time. That's like one of my things.
PROFANITY 10 - About 84 F-words and its derivatives, 3 obscene hand gestures, 21 sexual references, 34 scatological terms, 19 anatomical terms, 8 mild obscenities, name-calling (crazy, weird, stupid, idiot, tool, hooker, mutants, douche-pool, douche, ugly mug, fugly mug, ugly cockroach, maggot), exclamations (shut-up, wow), 2 religious profanities (GD), 9 religious exclamations (e.g. Oh My God, Oh God, God, Jesus, Jesus Christ, I Swear to God).
Honestly, I expected more. And how were the sex scenes? Were there sex scenes? I haven't seen it yet. There are really only two things I look for in a movie: dirty words, and sex scenes. I don't even need a story. Man, p0rno is the best.
Thanks to Paulio, who informed me The Wolf Of Wall Street had 569 f-bombs in it for an average of 3.16 uses/minute. That is about five times less than me talking in real life.
