Kerplopalopin
After a guy ejaculates inside a woman’s vagina, despite attempts at cleaning, it can stay present for rough 2-24hrs. During this period, at random (usually an inopportune moment), the warm cum will be discharged. This is kerplopalopin, it could be used as a noun or verb.
Omg, I was so annoyed, I was kerplopalopin yesterday in the middle of my presentation at work, and I totally lost focus.
