A smell so horrific, it can cause death to anyone who inhales it. The word originates from a rather large male from the North East of England.

The word can also be used to describe an obese, friendless person who is bad in bed.
Example 1:

"Bloody hell mate, what's that smell?"

"I'm not sure, but it's smells like Jack Stott's in the room"

Example 2:

"Christ, I met this girl last night and she was a right Jack Stott"
