mustaine 

Used in the phrase "to pull a mustaine", to yell "FUCK YEAH!" in the most random and usually inappropriate of times.

Named for Dave Mustaine, vocalist/guitarist for Megadeth; derived from the song "The Mechanix", in which Mustaine for no reason yells "FUCK YEAH!" near the end.

"How could she tell Dave was watching the game and not listening to his girlfriend?"
"Well, she was talking about her sick cousin, but his team scored a goal and he just pulled a mustaine."

dave mustaine 

The god of thrash. Personally my all-time guitarist. Unlike little teenybopper bands around now like Green Day and My Chemical Romance, Dave Mustaine's band, Megadeth, plays a little thing called music. He was kicked out of Metallica after writing a large portion of their better music (a lot of stuff off Kill 'Em All and Ride the Lightning) but never received credit. Metallica is an awesome band as well, but in my eyes Megadeth will always be superior. Dave Mustaine is known for being one of, if not THE, best rhythm guitarists of all time. He can write symphonies of complex low-end riffing and put in screaming melodies and incredible lead breaks in the same 10 seconds. His playing abilities are also OFF THE CHARTS as compared to other rhythm guitarists. I myself would give a kidney, leg, and maybe an eye just to have his right hand.

Did you go to that Megadeth concert last night? Dave Mustaine's hands were FLYING when he was playing that 3rd solo in Hangar 18!
