Things that people swear by, things that people regularly use, such as skincare products that only acne free people can use.
“OMG i swear by this acne wash that only works for people with normal skin! it’s like my HOLY GRAIL!”
A wonderful, tangible item or place that you miss dearly because it no longer exists and probably never will again.
"Do you remember those Rockstar Pomegranate energy drinks we use to drink in middle school? Those were so good. I'll have to add those to my holy grail graveyard list."
The hottest sexiest moistest man alive... yeah yeah yeah... often referred to as Mr. StealYourGirl is 100% ok with giving your bitch the Holy Grail
Boyfriend: FUCKING HELL WHY WERE YOU JUST HANGING OUT WITH CHRIS GRAIL?!?!??? DID HE GIVE YOU THE HOLY GRAIL?!?!???
