It's Friday... Friday.

In light of our recent # from our Twitter account, #thingsagrownassmanhasincommonwithrebeccablack, I reckon there needs to be a crucial distinction: Grown Ass Men may have many things in common with our friend Rebecca, but there is at least ONE area in which we differ greatly; Grown Ass Men are hardly indecisive when it comes to car seat choice. In fact, one of the telltale signs of a Grown Ass Man is the uncontrollable habit of loudly choosing his seat as quickly as possible, upon sight of the vehicle in which he is soon to ride.

I'm speaking, of course, about SHOTGUN.

Calling out shotgun is a compulsion experienced by grown ass men, sometimes when he's the only passenger.

Here's some pretty standard SHOTGUN customs:

• The call must be audible to the Driver
• The call cannot be made indoors
• Vehicle must be within sight of caller
• ReCall must be made if successful caller goes back indoors for any reason before entering vehicle
• If current shotgun occupant leaves vehicle for any reason, any other passenger may call shotgun and steal the seat.

Post up some interesting additional or variant rules if your Grown Ass group of friends abide by any.
