That stands for Swift Kick in the Balls. As in the several I’ve been getting from life lately.
Nothing bad, actually some good, not all kicks to the stones are bad. It’s just that they’re jarring. If you get kicked in the balls hard enough, you get lifted off of the ground and you don’t land in the same spot.
Sure it hurts. How could getting kicked in the balls not hurt? They’re your BALLS. But sometimes if you’re standing in the same place for a long enough time the only thing that’s going to make you move is an old fashioned SKITB.
