you sly dog you

A completely ironic phrase commonly used to define someone who does something mildly cool or impressive. This phrase should never be used seriously, as it ruins the joke, and makes you look retarded.

Lil cheggos, you sly dog you!

sly walking behind her move

When attempting to sit next to a particular person in a University of Sydney Economics lecture, this move should be undertaken. It involves isolating the person prior to the lecture, then walking up to person in a way that they will not see you (although if that happens, it can't be too bad). Once behind this person, follow them into the Economics lecture, thus following them into the row they decide to sit in, THUS, sitting next to them.
Finito.
Perfecto.

A1: Should I use the sly walking behind her move?

Sly eyeing

Slyly looking at another's body with sexual intent.

I could feel eyes on me when I walked into the room. As I turned around he looked down. I knew he'd been checking me out. He gave me the shivers. Such a creep sly eyeing me!
