stacked achievements

"Stacked Achievements" refers to the achievements system on the xbox 360. All 360 games have certain goals or challenges that when performed earn achievements. Each achievement adds to your gamerscore. A stacked achievement works like this: Say you have 8 chapters in a game and each chapter beaten earns a 10 point achievement. Chapter 1 beaten on easy would be 10 points, 20 points on medium, and 30 points on hard. If you beat Chapter 1 on hard your first time playing, you would unlock all 3 achievements for easy medium and hard. This would be a total of 60 points, and is called "stacked" because you earn all 3 without having to play through Chapter 1 3 times, once on each difficulty. Not all 360 games offer stacked Achievements, you can search the internet for games that do. Some examples include Gears of War and Halo 3.
"I beat Halo 3 on Legendary (very hard) my first time playing and got all the stacked achievements."

Short Stack

Short Stack is a pop punk Australian band, formed in Budgewoi, New South Wales, in 2005. It consists of three members; Shaun Diviney (lead vocals, guitar), Andy Clemmensen (backing vocals, bass) and Bradie Webb (drums, keys). The band formed at school when they were younger. Short Stack now have a new album called 'Stack is the new Black' and have many hit singles including 'Princess' and 'Sway Sway Baby'.
They have 'Short Stack TV' which runs on YouTube and spend a lot of their time talking to their friends on MySpace, and touring around Australia. When asked when they would tour New Zealand, they said that 'we got the name wrong and are going to Old Zealand' (or something like that).
Their audience ranges from 11-17 girls, and people from outside that age-group flame their band (just see some of the other definitions of the band).

Their band is around, love them or hate them, their here to stay.
Girl 1: OMG, did you see Short Stack last night?
Girl 2: Yes! It was the best ever, I bought all of the shirts there.
Girl 3: Which one is your fav though?
Girl 2: I think the 'Sway Sway Bradie' one.
Girl 4: Of course it is, you haven't taken it off for 4 days.
