Trailing is the sexual act of when you rub your pink finger against another man's anus, until they release poo onto the finger nail. They then leave it to dry, before scraping it off with their teeth.
Harry: I was out with the lads yesterday, when Colby suggested I tried to grail with Dan! To be honest, his poo tastes so nice!

Barney: Gotta love a bit of Grailing on the weekend! HU!

The ultimate source of bro truths and man wisdom. They are usually the last stopping ground before making major bro decisions, such as what fantasy player to draft first or what to do when your new girlfriend has a freak out for the first time. Multiple Broly Grails can exist, but are few and far between, and will naturally default into a general hierarchy, such as the Jedi.
Ask Dan for advice about the three girls you're dating, after years of crazy relationships, he's the Broly Grail for this type of thing.
