Compliment Inflation

When a person (typically a girl), receives so many compliments that the value of successive compliments decrease.

John: Ava, you’re so pretty!

Ava: Okay

John: Do you not like it when I say that?

Ava: No, it’s just that I get told I’m pretty all the time so the compliment doesn’t feel as special.

John: Oh I see, being called pretty has lost it’s effect due to compliment inflation.
