the attempt of one person to make someone else hip, especially when teenagers try to make their parents cool by repeated exposure to modern music, slang, culture, etc.
What an attractive lady does to a man by provocatively swaying/undulating her waist.
I don't need a hot chick to "move her middle" at all to get my attention --- all she hasta do is get naked. Merely showing me her smooth shapely "merchandise" is all it takes to turn me on... no need to hipnotize me!
