For everyone in this thread: there is a “parent’s guide” section for every movie on IMDB that describes the objectionable scenes in every category. Spoilers are hidden, but if you’re going to watch a movie with sensitive people, then it is worth putting up with spoilers to know the extent of the awkwardness that awaits.
Example for The Lighthouse (with warnings about what OP posted): https://m.imdb.com/title/tt7984734/parentalguide/nudity
I would like to clarify:
There is no piss inside beans/toast that needs to be extracted.
