Lane splitting etiquette

[xstortion]

K some I am running a little late to work today. I am in dead stop traffic so I decide to lane split for a bit. I am just coasting along and I see some guy swerve into the middle in front of me causing me to skid a little bit. At first I thought he was tryin to switch lanes but then I realized he was just being an ass.

What should be done when this happens? I was thinking about kickin the shit out of his door or something.
How do u guys feel about it?
