anpissitation 

The feeling of being next in line for any event, and the excitement of feeling next in line for said event makes you feel the need to go to the bathroom.

A play on the word anticipation; anpissitation.

My girlfriend was next in line to get her face painted, and was suddenly struck by the gravity of the event and felt a strong urge of anpissitation. She left the line to go relieve herself.

Anpissitation 

An"piss"itation: that feeling you have, after having to take a leak, when you reach the toilet and as you are starting to undo your pants and you can feel the piss coming out any second whether you are ready or not.

"Man I had the worst anpissitation and now I need me some fresh pants. Hahahahaha

Anpissatation 

The feeling that you have when you really have to urinate!! The closer that you get to relief, the more intense your anpissatation becomes!!

The closer I got to the toilet, the stronger my anpissatation became. It was almost painful!
