'Pat n Debbie Boone' is my fave. (Mnemonic and fill)Its just words to give the feel. It's not actual terminology, just a mnemonic tool for drums, that's all. So is:
1 trip-let 2 trip-let
You can replace the mnemonic phrase with any other one that floats your boat. Ergo "buck-et of fish" can be "go yourself" if you wanted.
