The term used if a person shits out of something, goes home early on a night out, or basically stops doing something that in all situations should be done with ease.
E.g.
A person goes home from a night out really early
"You propa half-seshed it last night didnt you, went home early"
And
"Are you coming on the new oblivion ride at alton towers?" "No" "You Half-sesh"
