The Holy Grail is a term used by porn stars, can be used as a noun, verb and/or adjective, and is basically when a female porn star takes a cock in her arse, a cock in her vagina and a cock in her mouth, all whilst simultanously giving two handjobs.

In my experience, The Holy Grail is a trick best left for the pros.

The Holy Grail, also seen in the movie, Indiana Jones and the last crusade. Near the end of the movie while lost inside a maze from hell inside a mountain, at the core of the underground lair we find a room full of cups, some beautiful some not so great. Nonetheless, one of them is the grail. He who drinks from the correct Cup (Grail), will have ever lasting life! Although, he who drinks from the wrong cup will shrivel into a really tacky looking skeleton, and then be blown away by some random wind no one knows's where it came from but, regardless it is there temporarily.

The following example is not from the afforementioned movie though, it is from the Monty Python movie... my fav part :
When trying to find the Holy Grail, the quest was abruptly stopped at the bridge to oblivion!

The Holy Grail is the tomb of Mary Magdalene and the Sangreal documents, which prove that she was Jesus Christ's wife and that he was a father.
This theory is discussed in the books Holy Blood, Holy Grail and The Da Vinci Code.
The Holy Grail is not a cup, but rather a metaphor for something much more important.
