Man Muck 

Rancid bodily secretions that mingle in the cracks and folds around the male anus, ballsack and chode; creating pungent yet sickenly appealing scratch and sniff opportunities.

Though the cameras of the world were pointing his way, the German football manager couldn’t resist reaching deep inside his trousers to scoop up some of the sweaty discharge that had collected deep inside his arse crack. As he drew his gruby fingers towards his mouth he inhaled deeply, the intoxicating aroma of last nights spunk and this morning’s skid marks filled his nostrils. ‘Who cares about the score when you have all this delicious man muck collecting in your pants!?’ He sighed

mother mucker 

When you want to call someone a mother fucker, but don't want to get in trouble.

Origin:
In Texas Hold'em, you can fold your hand and throw your cards into the "muck". Now imagine someone does that to a mom. Pretty messed up.

"Hey why do I not get a raise this year? I'm outta here you mother mucker"

"Oh this mother mucker just cut in front of me."
