1. A play on the name Kyle Rittenhouse and the term Shithoused.
2. Getting so drunk you do some crazy shit like mobbing across state lines with an AR-15, completely horned up offensively just wanting to cause havoc.
Man I got so Kyle Shittenhoused last night that after the bar I fell asleep in the drive thru at jack in the box and the guy working the window had to wake me up…… didn’t get a DUI though.
