This Is Spinal Tap (1984) More at IMDbPro »

Some explicit innuendo, often in the form of lyrics.

Suggestive scene involving tight trousers.

A pickle is found in someone's pants.

Several references that sometimes contain explicit language.

None, except a couple of arguments (which are usually played for laughs).

Fairly strong profanity throughout.

In the 2nd half of the movie, Nigel uses the word "fuck" in about every other sentence.

David and Nigel have an argument where just about every other word is the f-word.

Highly suggestive lyrics feature in most every song the band plays.

Overall, there are 29 uses of the word "fuck" and it's derivatives, (but unless you have subtitles on, a couple of them are slightly hard to notice) as well as a few uses of milder swear words like shit, damn, hell, etc.

Some smoking

None of note.

(spoilers) The scene where Nigel is carrying news to the band and gets in a fight with David is rather emotionally intense, seeing as they've known each other for 30+ years.
