"I'm going for an Izzy Stradlin" is the one I kept coming out with - mainly to confuse people for the fun of it. The reference being that Izzy Stradlin was the other Guns n Roses guitarist, ie the one that wasn't Slash. So it just meant "I'm going for a slash".
Just a nice image I've been having - which is that of a wet t-shirt made wet with a dousing down of warm pee
The thought of a cropped white t-shirt dripping down afterwards - and I can imagine a girl with such a wet t-shirt on riding on a guy with the pee still dripping down her belly as sex takes place.
A nice, warming image
The lower inhibitions of being a kid made for many opportunities for this kind of thing.
Back in the adult world, I'd quite enjoy doing a group, say three people, crossing streams - of any gender of peeple involved.
Back quite a few moons ago, someone I knew and I would go to the toilet and pee at the same time from different sides of the toilet, so that the streams were going at 90 degrees to each each other. The challenge (not a wholly difficult one) was to aim the two streams so that they collided.
I'm guessing this is not totally uncommon. It was always good fun.
