Wilting

The act of stretching the urethral opening of the penis out so much that you can fit another penis (or various large objects) inside.

Friend 1: “Hey bro, do you want to have a wilting session later?”
Friend 2: “Sure dude! We can wilt so hard!”

Plaining

The act of cutting off circulation of your penis so much so that it becomes purple and numb. The word was popularized around the Portland area.

Friend 1: “Hey bro do you plain?”
Friend: “Yep. I practice plaining until my dick turns bright purple. It’s extremely pleasurable and it gives me better orgasms!”
