what does “sweating like a banshee” mean?

That the person is sweaty.

I’ve never heard of that. just screaming like a banshee which means your screaming really, really loud. In Scotish and Irish tradition banshees wailed at the death of certain noble family members.

I thought the term was screaming like a banshee.

Nothing…banshees don t sweat!!!

YOU SWEAT SO MUCH. YOU ARE TOO DAM/N HOT.
