Walking down Kingsland Road last week

I heard a man's voice hiss
  

move your dirty body out of the way  

I was going at quite a clip anyway, it was a broad pavement and he actually couldn't walk any faster than me so we were going along side by side.  I wasn't sure I'd heard correctly so I said

Sorry?

He looked sideways at me and scowled and managed to walk a little ahead of me so I could get the best view of his stained and unpleasant sweat pants.

He was around 30, a lot bigger than me and clearly an Angry Man so, although in theory I'm all for calling people out and standing my ground etc. I figured that this might not end well for me - it was becoming a stand-off - so after walking beside him for just a couple more minutes I crossed the road and we paralleled each other for the next mile until he turned off.
