What does it mean when your MIL flashes?

When someone refers to their "MIL" flashing, it typically means that their mother-in-law is showing unexpected or surprising behavior, often in a playful or humorous context. However, if taken literally, it could refer to a situation where a mother-in-law is revealing more skin than socially acceptable, which might be shocking or inappropriate. Context is key to understanding the intent and meaning behind the action.
