Hurdler Michelle Jenneke -- Drops New Ass Video

Australian hurlder Michelle Jenneke -- the woman who's cute jiggly warm up dance captured the hearts of pervs everywhere -- is turning it up a notch ... in a steamy new video for WorldstarHipHop.

Here's what you need to know:

Michelle runs bleachers ... in booty shorts.

Michelle trains ... in booty shorts.

Michelle hangs out in a bikini (which are booty oriented by default)

Michelle does her famous warm up dance, then hurdles, in shorts that prominently display -- you guessed it -- her booty.

The final scene ... a group of black guys applaud (we're not making this up).

Enjoy.
