muck it up

After a good doggie style romp, the jizz left on the tip of your cock gets rubbed into the chicks bunghole. A little poop gets mixed in during the rubbing and you muck it up.

After banging the bitch doggie style, I blew on her back. Then I mucked it up for a bit, before banging her sister.

Muck It Up

Muckit is when you take your cock and push it around in your bitches asshole...you smoosh around her shit and your gizz.

After I was done banging my bitch, I mucked it up.

Crate Muck-up

The time period when Valve released a TF2 update with spaghetti code that forced the crate series to always drop unusuals. This resulted in the unusual market crashing with absolutely no survivors left.

The Crate Muck-up was one of the worst disasters in TF2 history.
