Barshit can be a synonym for the word bullshit.
If someone cuts you off while your driving, you say "thats barshit"
Barshit also tends to be
followed by the word unherman.
You can pronounce unherman with a silent H for a more effictive saying. So it would sound like unerman.
Barshit and Unherman both
originate from the Armitage
household, which has been adopted by the Hurdons, and other families.
Both words sound better when used in a Country/Hick accent.
