To indicate someone is miserly, the Dutch would..
-
Slap their elbow
-
Glide the forefinger down the nose
-
Make a fist
-
Hit on arm
The Dutch gesture for indicating someone is miserly involves gliding the forefinger down the nose, starting from the bridge and moving downward. This gesture specifically references the Dutch cultural stereotype associated with frugality, though it should be noted that such gestures can be culturally specific and potentially offensive.
In Dutch nonverbal culture, gliding the forefinger down the side of the nose is a traditional gesture signaling that someone is stingy or miserly (cheap). Slapping the elbow, making a fist, or hitting one's arm are not documented Dutch gestures with this specific meaning — they appear as plausible-sounding distractors without the cultural grounding of the nose gesture. This is a specific piece of cross-cultural body-language trivia rather than something derivable from general reasoning.
