Waterfall

1. a giant, monstrous quantity of sperm travelling upstream, weaving its way through the ejaculatory ducts until finally finding its way to splash unceasingly upon an unfortunate sock or eyeball.

the result usually leaves the victim confused, without recollection of the event, in pain, yet yearning for more.

2. water falling

Intelligent man: Nancy asked me to blast a waterfall in her eyeball, I told her it wouldn't be easy.

Lesser man: what do you mean you ignoramus, just do it!

Intelligent man: It isn't like I can conjure up a waterfall just like that moron, it takes years of practice
Lesser man: whatever Lester, I'll do it now
Intelligent man: 'sighs'
