Ass-mud attack 

On the day after a very heavy drinking session, the victim can sometimes feel his/her anal sphincter almost give up, unexpectedly at an inopportune moment. The fear of this causes a serge in adrenaline which can momentarily provide the victim with enough power and control to prevent the full evacuation of the bowels. This process happens in less than a second but can be repetitive over the course of a few minutes forming a type of 'attack'. e.g. asthma attack. This can be exasperated when in a seated position (due to the body being use to this position when defecating) and on some form of transport. E.g. on a plane, in a car or on a train, etc.
A victim of such an attack usually suspends all rational thoughts, objectives and tasks as their new primary objective becomes getting to a toilet as soon as humanly possible before the worst happens.

"I went out after work last night with a friend and had way way too many beers". I had an ass-mud attack on the train on the way into work this morning".

Mud asser

The term Mud asser originates from the name Mudacer. It's most likely to be the name of an extremely obese Afghan guy who does art. He rarely takes showers and smells like piss mixed with sweat. He does not wipe his ass, hence the name "Mud asser".

Guy 1: You're such a mud asser!
Guy 2: But I wipe my ass!
