Wabash Avenue in Terre Haute is a popular place for the average hautian to hang out. Usually, bashing is done by sitting on a couch ("sofa") in the back of your pickup and driving up and down the 'Bash, usually soliciting young women to flash their breasts.
Dude, I got a new futon... wanna grab the truck and go bashin?
To bash is to grind and sweat at something, be it a game, a sport, anything. Bashes will become obsessed with a particular thing and spend a lot of their day doing it
