P/E ratio
The Pussy-to-Effort Ratio. It’s how much a guy gets from an activity compared to how much of a mess it makes him.
Going to a concert with friends? That’s a 6/10 P/E ratio if he gets a kiss.
Drinking 10 beers to talk to a girl? That’s a 2/10 P/E ratio.
Wearing a fake beard to impress a girl? That’s a 3/10 P/E ratio.
