A cheek buster is when you blow up your cheeks whilst biting down on your lips. Blowing them up and blowing them up as much as you can makes it a cheek buster. To the max!

A sound that comes from air in the top half of your cheeks seeping out. Some say that it sounds like a cat 'meowing', some say it sounds like Abu from 'Alladin' some say it sounds like a duck, but all us smart people know that it clearly says 'bow'.
