Muckout 

The verb, muckout, is the action of going to a club/bar or any place where the consumption of alcohol takes place and seeing to it that the female attendees are sexually satisfied by the end of the night. Some consider this a duty, a responsibility, an absolute tenet whilst others treat it merely as a hobby. There are some that are better at mucking out than others however it is the intention to muckout that is key not the success of the act itself.

Muck out 

Formed from 'mucking out' or cleaning the poo from livestock dwellings.

However, more modernly, it is in reference to laying the hammer down on a big babe's butthole. Hence, cleaning the poo from her balloon knot.
