look up any word, like ratchet:
any pedestrian that gets in the way of a bike messenger/courier or cyclist; whether pedestrian is crossing the street, on the sidewalk or on a hiker/biker trail.
"Dude that flesh pylon crossed the street without looking both ways so I had to nail him."

"I hit this flesh pylon on the sidewalk cuz I was scoping out this hottie on a bike."
