The "increase" sign can be used to mean such things as, "get a raise" or
INCREASE / get a raise / gain weight / go up:
The following sentence
has two interpretations:
Interpretation 1: Have you recently gotten a raise?
Interpretation 2: Have you recently gained weight?
Note: If I were asking if someone recently gained weight, I'd also
puff out my cheeks a bit while doing the "increase" sign.
Note: The above version is NOT recommended for use with your wife.
Don't ask me how I know.
