My home town is Portishead, Somerset - locally called "Posset".
So, people from there are Possetonians!
I have never found an explanation as to why the town is called Possett? 
I've just come across this thread again and I remembers as a child us bains (Hullensian for children) were given possets when we were poorly. Our mother gave us a hot sweetened milk with the addition of rum. I believe the addition to the milk of any other alcohol with or without spices will do.
