A sexual act practiced by entire engineering classes. Engineering fields historically have had more males than females, as a way to engage in sexual acts where females are distributed evenly among males the whohr's circle was invented. All the girls in the class sit in a circle facing outwards while all the guys stand in a circle facing inward, surrounding the girls circle. Essentially a bukkake but with an emphasis on even distribution.
"Hey tyler, are you still a virgin? We're almost about to graduate!"
"Yeah."
"Don't worry dude, you have to lose it when we do that whohr's circle thing after the ceremony."
