"HG" can be used as a term in the makeup world, and stands for "Holy Grail". It basically means that the product being
discussed is someone's absolute favorite, something they swear by, and a perfect find.
This new Maybellinemascara is my HG! I've used plenty of others before it, but this one is the best!
When a bunch of guys suddenly become interested with one girl all at once. The said "hot" girl loves the attention and starts to take her new status for granted.
When a girl becomes really self obsessed and sometimes mean because a couple of guys seem to think shes hot she can be classified as having HGS.
