guster 

A band whose support is mainly grassroots, collected through incessant touring. They aren't mainstream, and therefore aren't widely known or popular, but have an incredibly large fanbase. The members met in college and started a band, originally titled "Gus." The name was changed later to Guster, and has remained so ever since.

Guster is a kick-ass band and anyone who says otherwise is wrong. Their harmonies are excellent, lyrics innovative, and didn't have to sell out to be sucessful.
They've put out several albums since their beginning in the early 90's: Parachute, Goldfly, Lost and Gone Forever, and Keep It Together. I own all four, so should you.

Kid A Who Wouldn't know good music if it hit him in the head:Hey, what's your favorite band?
Kid B Who's Awesome:Guster.
A:WTF IS GUSTER?
B:A great band, here go to their website.
A:Ewwww I hear a new sound that doesn't sound like everything else pumping out of my pop/rock radio. I HATE IT.
B:You suck. Go listen to My Chemical Romance, Fall Out Boy, or someother piece of crap music.
A: Okay, since you told me to, I will.

guster 

the greatest band ever, NOT from Massachusetts as many people think (they grew up outside of the state) but went to Tufts in Massachusetts so they consider themselves natives (which is cool by me!)

Guster rocks my world

Guesterbate 

The act of masturbating while staying as a guest in someone else's home. Particularly entertaining if it is in the home of someone you do not like.

Harper: "Hey Chuck, I'm going home tomorrow, so you can have the room to yourself."
Chuck: "Thanks man, but I don't need it."
Harper: "You sure? I've been around all week."
Chuck: "I'm good bro, I guesterbated in JJ's room last night while he was asleep."
Harper: "Awww man that's dirty, wish I woulda thought to do that."
