Any wonky ass looking bass typically used by butt-rock, nu-metal and jam bands. Usually are incredibly overdesigned to provide balance and playability but somehow never look pleasant. (term used by Pat Finnerty in the post Kravitz-Bowl to describe the bassist of Puddle of Mudd's bass)
"Hey bruh, have you seen my new Warwick?"
"You paid a fucking grand for a shape-bass?!"
