The oily, smelly residue that is a result of the accumulation of sweat, dirt, and left behind stuff between your ass cheeks after a long run or other sweaty physical training session.
My underwear was full of jockey butter after running a half-marathon.
I can't believe it's not jockey butter!

A man who receives anal sex and allows the other man to shoot a load (or two) inside him, then saving it in his anus. He then goes home to his lover and fucks him in the ass with the other guys cum still in his ass. The cum jockey is probably high on crystal meth, thus allowing this minor lapse in judgment over what is in good taste and what is not. He, however, finds great pleasure in the fact that he is still full of jizz. This must take great muscle control and a true deviant piggy mind.
John is a total Cum jockey! Bill filled his hole twice before he went home to Steven. What a weird way to have a 3-way!
