The byproduct of a masturbation session where your ejaculate flies from your penis with such force and ferocity that it lands on a distant shelf. The accumulated ejaculate can be compounded over time to form something similar to a Sploogy (an Emmy made of pure cum) or an Oskeet (an Oscar make of oxidized spunk).
Girlfriend: "Aww, that's cute. What's that award on that shelf!"
Guy :"Baby, that ain't no trophy. That's just shelf jelly."
