This enlarged looping clip looks like a running person to me. They seem to be removing some sort of upper apparel (jacket, sweater, etc.) as they run. It's not a pullover thing, but instead opens at the front. The runner starts removing it by dropping it down off the shoulders, then to the elbows and forearms (sleeves would come off last). I don't think the garment is fully removed in this loop.
This comes from
Bigfoot Encounters, where there is much information about the MDF and other clips.
