Put You Down - This is from Justin Bieber's stupid song where he is promising a girl he's gonna put her down (fuck her) but in reality he is only talking to his hand, and he then succeeds - he realizes he will never fuck a girl and he put's it down.... This can be said to a girl to let her know what your about.
Pull(ing) Your Dick. Similar to sitting on your hands, not contributing, or just plain fucking off. Often used to describe actions of a useless team member or friend.
Are we hanging out, or are you just gonna PYD all day?
I was getting real work done while you were busy PYD.
You can sit around PYD later; right now we have to go!
