Your one friend, everyone has one, that continues to defie all logic by "one uping" the last most stupid thing you've ever heard of.
Perry, "your brother", was tailed by the popo last night. Instead of going quietly, he ditched his truck, ran trough a corn field, called a crack whore to come pick him up, filed a false report for a stolen truck, and denied he was even in the area. Wow, I want to party with that guy.

An absolutely diabolical insult, extremely similar to "Your Mum gay, your daddy lesbian, and other such". This is an insult on a scale with power similiar to that of God himself, so, unless you want the universe to crumble before you, do not use this terrfiying phrase.
Carl: Your Mum Gay!
Dylan:Your sister a mister!
*The Earth begins to shake as Carl readies the blow to Dylan"

Carl:Your brother your-
Dylan:DON'T SAY IT CARL!
Carl: I must.... YOUR BROTHER YOUR MOTHER!

*Cries are heard from across the universe as, atom by atom, molecule by molecule, the universe begins to crumble away, for not even God can save us now*

The secret god of insults; this forbidden phrase can erase the people listening to it from existence
Person 1: Your mom gay
Person 2: Your daddy lesbian
Person 1: Well your granny a tranny
Person 2: YOUR GRANDPAP A TRAP!

Person 2 falls onto the floor and is in great pain
