Va-insecure

AITOOW wants credit for coining the term "vainsecure"? It's a combo of vain and insecure. It describes people who showboat or run other people down to make themselves seem more important. The proponent is overcompensating (to the point of vanity) for their lack of self-esteem. Think about most rap stars or cornerbacks or mean girls or Instagram posters or vulgar women.
