look up any word, like fleek:
 
1.
Derogatory term for a female, implying superficiality, materialism, vanity, and a hollow emptiness. May also imply promiscuity, but not necessarily.
Paris Hilton is a vapid cunt, because she is completely materialistic and empty inside.

**In the future one may want to know all the possible meanings of a term before referring to others as morons. :D

2.
cliche internet catchphrase mainly used by idiots who don't know what "vapid" means. they think it means ditsy, air-headed or something like that, but really it means "lifeless" or "boring".
douchebag #1: paris hilton is such a vapid cunt! vapid!!! vapid cunt!
asshole #2: shut the fuck up moron, learn to use a dictionary.
