look up any word, like fleek:
 
1.
diamonds or other jewellery that is fake.
my friend Joe bought some Foolgazy Diamonds From the Jeweller the other day, he was rather upset.

2.
Only a fool looking at something fake would believe it is real.
It is a fool gazy diamond meaning someone thinks it is real when it is not.
