Wednesday Trim
A Wednesday trim is when you trim your pubes on a Wednesday in anticipation of getting lucky on the weekend.

It is important to trim on a Wednesday because it gives you time to grow a little stubble, and get rid of the razor burn so it doesn’t look like you shaved just for the weekend.

Person 1: “Dude my ex girlfriend is coming over Friday, should I shave the pubes before she comes?”

Person 2: “Bro, you should go with the Wednesday Trim, that way she knows you didn’t shave just for her.”
