gainiac 

a musician, usually a guitarist, addicted to ridiculously high amounts of gain/overdrive on their amp and always in the pursuit of more ball-shaking, pinch squealing, brutally chunky and thick, ear splitting, face melting, body crushing action, that is distortion

Any guitarist who has had an amp and turned it all the way to 10 wishing it would go to 11!!! Van Halen, Dimebag Darrell, Angus Young, Me!!! Amps such as Mesa Boogie Triple Rectifier, Bogner Uberschall, ENGL Fireball, EVH 5150, Krank Krankenstein+, Soldano SLO 100, Peavey 6505, Bugera 6262

Alex: Eddie's been fuckin with his amp and now it sounds better than ever!!

Eddie: ALL IT NEEDED WAS MORE VESPENE GAS, I'M A GAINIAC!!!

Gayniac 

#1 One who is same sex oriented and acting like a maniac. #2 One who is acting gay but also acting like a maniac.

AL was at the Dark Lady in Providence and totally saw his boyfriend kissing another boy. Whilst yelling and screaming Al went over and slapped the piss out of his boyfriend. He was acting like a complete Gayniac.
