Duff

Duff is a sweet desert or pudding eaten after the main meal.

It is never a savory meal like post-scran-scran, and is not eaten before a meal like pre-scran-duff.

Napa - Great scran mate, whats for Duff?
Bill - Triffle
Napa - Awesome!

duff

The leftover remnants of meth after smoking. Or small crystals of crappy meth that can be found on tables, etc, in a meth user's home.

We opened to basement door and told Jeff's uncle it was time to go. He screamed "Do you want me to do this F*kking Duff, or what!!!!??" while pounding a table.
