I remember this movie where a couple of Americans are with a tribe in Africa, accompanied by a guide. Maybe they are husband and wife or just friends.
They play the patronising, ignorant tourists and when the locals are practicing a tribal dance, the woman stands to dance with the chief. At the end, the chief tries to pull her to his hut (presumably to have sex) and the woman says: “dancing does not mean this”. The guide, also American but well versed in African customs, says: “that is exactly what it means”.
It is a classical Hollywood movie, maybe from the 60s. I watched it on TV, decades ago, dubbed to Spanish, but I am sure it is an American movie. I do not remember if it was B&W or colour.
