ghost cum
That Perplexing cum that you thought you had cleaned up after spanking the dolphin.  The cum that, to your dismay, soils you boxers, pants, and sometimes shoes.
(A man pulls up pants after taking care of business) "Goddamnit, I thought I cleaned all that shit off!  Now it's all in my boxers and dripping down my leg!"

It looks like he should have checked for ghost cum!
