A word used to describe an old stale smell. Particularly if someone else thinks it is a good smell.
Sharon puts on this rose water and thinks she smells great all day long, but really she just smells like old lady tuppa powder.
A tuppa is another word for a vagina. This is a slang word from mid-Maine.
I walked into the stall here this skanky chick had just come out of, and I was like: "Wow,that girl's tuppa stinks!"
