shag-nasty
slang Particularly nasty or disgusting. The room they gave us was shag-nasty, but it was already 1 AM and there wouldn't be another motel for several hours at least. Judging by the shag-nasty gunk that came out of their engine, I'd say they haven't changed the oil in years.
shag-nasty
mod. nasty. I want out of this shag-nasty mess.
