Waiting for your permission to load the Instagram Media.
Bam's obviously frustrated at the lack of response in the video, and claims when no cops showed up, the whole neighborhood told him to go handle it ... and clapped when he was done.
Bam Margera recently found himself throwing down with a stranger -- a fist fight captured on camera, but Bam says he was simply protecting himself and friends ... TMZ has learned.
