The feeling you get when you see an ex with someone else. You really don't want them back but they are like a fire hydrant and you are seeing someone else piss on your fire hydrant. Which enrages you and makes you want to piss on that fire hydrant again.

This sexual move is very relieving, but takes a while to set up.

First, have sex with girls for a month, but before finishing, just pull out and stop.

Next, on the last day of the month, finish.

Last, watch as your sperm spews out of her ears and mouth at uncharted speeds. Like a fire hydrant.
