When two people squat with their backs against each other and simultaneously take a shit. This positional adds stability to the normal solitary squat one would do when taking a shit anywhere besides a toilet. This can be very effective when in hostile, or bear territory and need someone to watch your back.
Me: Man my stomach hurts
Josh: Mine does too!
Me: Time for a Double Dump! Bring your beer!
The act of being upset over a very menial situation such as not being invited somewhere or having information withheld from you unintentionally. One whom becomes butt hurt easily also is great at verbal accusations in lieu of physical altercations.
Josh: Dude... no invite. COOL!
Chris: Ya'll get butt hurt too much. Here's some ice for your bruised ego.
Kyle: I need a hooch.
