The act of taking a handle, specifically of McCormicks, Apple flavor, and tilting it until it is perfectly 180 degrees "vertical" and drinking as long as you can.
"We're going back to his place to take a couple casual verticals."
"Good Morning, I'm so plyat, want a vertical?"
"Hey, he looks pretty gone/blacked out/hamsuaced, wanna vertical?"
Hey wanna go take a few verticals in the gazebo?
Hey wanna shot? no.. I'll take a fucking vertical!!!!
My summer is going to consist of verticals and vertricals..
