The sexual act of having a women laying on top of the man. The man proceeds to wrap his arms around her while pinning her down while thrusting so fast that he is like a machine. This incredibly fast action creates such stimulation that the women immediatly becomes paralyzed with pleasure.
Last night was incredible, my boyfriend gave me THE SHIFF and I could not even move. He moved his hips as fast as a jackhammer!

Onomatopeoia for the shaking of a salt shaker
Friend: Why isn't this salt shaker working?? *rapidly shakes and turns it in frustration* *shiff* *shiff*

Get the Shiff mug.
1. A person who, in their rejection of conformity, becomes themselves a conformist.

2. A person who behaves a certain way because it is socially acceptable, as opposed to personally comfortable.
1. "That one kid dressed all in black with the chains on his pants told me that he was a non-conformist. What a shiff."

2. "I hate these tight pants, but a lot of other guys wear them, so oh well. Does that make me a shiff?"
