When a man about to have sex with a girl (or guy if you're into that kinda thing) turn out the lights , penetrate him/her, ejaculate, turn out the lights, and find out it was a watermelon the whole time.
"Tommy WHAT THE FUCK ARE YOU DOING!"
Tommy: "Well looks like we have a case of Watermelfunction."
The waterfall 2.0 is a spin-off version of the sex position: ‘the waterfall’.
What’s different is that the position is in a running shower instead of from a bed or couch. In a running shower it’s alot more like a real waterfall so that’s what makes this positon so much better.
Due to the fact there’s no bed in the shower the man would have to adjust his position slightly.
Jack: (To his girlfriend) we should try that new sex position ‘the waterfall 2.0’ later
Jill: What’s that?
Jack: It’s like ‘the waterfall’ but in the shower
