The Big Bad Swim (2006)

This film would probably earn an R rating. There is a scene where two characters are clearly having sex. Both are nude, but although you can't see nipples or genitals, it's fairly graphic. One of the characters is a stripper, and she is seen working, but you never see breasts or genitals. It looked like another dancer's breasts are probably visible in the background. Lap dances are shown a little bit but not too graphically. The stripper goes to work a party and later mentions getting spanked by some guys.

One character gets 'maced' in the eyes, he falls and hurts his knee.

The f-word is used a few times, and I believe some other profanity, not too prominently. One character speaks harshly of a small dog, and uses profanity forcefully.

Characters are seen drinking a few times, and speak of being drunk. A lot of the characters smoke. Marijuana and cocaine are mentioned.

There's a scene where a lone woman in a locker room and in a parking lot at night feels threatened, and is startled by a man.
