An ejaculatory phenomenon that is far worse, and far more annoying than "precum". Postcum is the same as precum but often contains a little truecum aswell.
I knew Tana was going to be at work today so I jacked off then when I was done, changed pants. Too bad I forgot about postcum. On the way their some remnants leaked out of me penis and stained my freshly ironed khakis.
