A cock mungler is a real jackass.
To mungle someones cock is to do something that just destroys them,
like in a game.
To get your cock mungled would be to get destroyed,
like in a game.
You may have to use various objects to mungle somones cock.
Like a gold
fish, a packet of crayons a bucket of vasiline and a zippo lighter.
A true cock mungler can mungle someones cock with his barehands.
