To make a note so you don't forget something. It was a saying back in the day before cell phones and computers. When people would use wood pencil on paper.
Person 1: Did you get the directions to your cousin's place up north?
Person 2: Yeah.
Person 1: Jot da woo down before you forget it.
Girl: Did you bring your list?
Boy: Yeah, I jot da woo down.
When shooting down in NHL 2007 for X-Box 360, often when trying to shoot the player would dump the puck into the corner or just hold onto the puck to long.
I will never tie this game until the third period because of the down factor. I hate shooting down.
Getting the puss or getting head.
