A word invented by a Crackhead Named Gridly, whos aliases include "Griddles", "Grid" "Griswold", and others. Twompson by itself means 20, like 20" car rims. But when used with the word "Dub" it can describe a 40 oz. Beer.
"I need some scrilla so I can go down to the Liqour Store and buy some Dub Twompsons and get crunk. Shayzzz...."

Also,"Peep the twompsons on the cadillac right there. Shayzzz..."
