When someone compliments an unattractive
individual to make that individual feel
better about themselves (actually meant to boost their self esteem) but it’s actually not true; the individual then mistakenly takes it
seriously from there on out and has an inflated ego.
Example:
Sarah thinks she’s hot shit since she got those breast and
butt implants but she’s actually a “compliment gone
wrong”.
Dave sure has been acting like a “compliment gone wrong” ever since he got those new hair plugs.
