"Dime Piece" is a combination of the words "Dime" and "Piece". It is used to describe the small bits of an american 10 cent coin that has been broken into multiple parts
hey man, i just broke my dime.
"don't worry i have an extra dime piece here"
cool, now i have enough to but some tasty, smooth pudding
a clothing piece worn by only the most rad-fab sexy pimps and other important people. It generally represents a large amount of plad on someone's get-up. I like uber plad because i am fashionable and good looking.
