Acronym: AIS

A poker analogy which applies to a one night stand that's dragged out because the girl still hasn't given it up.

The player feels they've invested too much to back out now.
John: What's Doug still doing with that girl? It's been 2 months and he still hasn't sealed the deal.

Mike: He's got classic All in Syndrome, he's spent weeks as her 'boyfriend' and has yet to reap any benefits.

John: That's weak, he needs to man up and cut his losses.

Mike: Agreed.

A condition which causes sufferers to never change out of their pyjamas.

People take their children to school in their pyjamas, go about their business, go to the supermarket and go about their daily lives wearing their pyjamas. In rare cases, people like this actually have jobs, but this is almost unheard of.
Boss: "Why are you wearing pyjamas to work?!"
Employee: "What's wrong with that? It seems perfectly normal to me. I wear them everywhere."
Boss: "You must have All Day Pyjama Syndrome. I'm sending you to The Priory..."
