Definition:
The card you pull on a friend to get what you want. It cannot be turned down without making the "bro" out to be a bad friend. Usually stated..."If you were my bro..." with no need to finish the sentence. * The Bro Card may never be pulled on a bro card itself.
Example:
1- C'mon man hand me a card under the table.
2- No Dude! I dont cheat!
1- If you were my bro.... (The Bro Card)
2- Ughhhh!! Alright! Here!
1- Thanks BRO!
*1- If you were my bro you would eat a booger."
2- If YOU were MY bro you wouldnt ask me to.
