Well, seeing as I usually have a drink on me when I'm out and about, it would probably go something like this:
I put as much of my drink as I can into my mouth. Then, once the guy gets close enough, I spray it in his face. While he's trying to get pop out of his eyes, I close the remaining distance, and just go to town on the guy.
