guibass 

A guibass is a cross between a guitar and a bass. A guibass is made by taking an old shit-ass classical guitar and prying out the tuners with a screwdriver and replacing them with bass tuners. 4 bass strings are then added. This instrument makes virtually no noise.

My friend Mike made a guibass out of his old classical guitar. I slapped him and called him an asshole.

Guitass 

Bass guitar, played by those who do not own a bass guitar. It is played by playing on only the E and A strings on a guitar.

Guy #1: "Hey, man, can I play your bass?"

Guy #2: "Nah, man, I lost it. All I got is my guitar."

Guy #1: "Then how you been practicing?"

Guy #2: "I've been playing guitass!"
