The Wolf of Wall Street is absolutely filthy with its language. Nonstop usage of the F-word, and very graphic sexual dialogue is heard throughout. It never stops.

3 uses of cunt
70 uses of shit
10 uses of cock/cocksucker
Countless uses of milder language including dick, twat, pussy, ass, bitch, etc.
