Text:

Parents would tell their children that if they make funny faces too much, their faces will be stuck like that forever.

Context:

The informant was told this as a child, and noted that it was said generally either in jest or as a light way to discourage them from being immature/disrespectful and making faces all the time. They also carried this on and said it occasionally to their own child, though mostly in teasing.

Analysis:

This phrase was and is used by parents as a funny but somewhat “scary” way of keeping their children from making faces all the time. It shows how certain beliefs are born from ways of keeping children in check rather than innately from fact or fear.
