What is this smilie doing?

Sorry for the retarded thread, but I was trying to figure out what this smilie is doing: :hand5:
I see it used all the time. It is just called hand5.

I think he's laughing at the previous statement. That's how I take it.

I always thought it was "poking" or "prodding".

yeah, I thought it was poking fun at whatever the previous statement was. To me, it looks like it's laughing while poking.

It looks like it's...giggling in agreement?
...snickering at or mocking?

I dunno. Good question.

oh ok. Thanks guys (and gals)

I think it means "laugh at what I just wrote"

I thought it was DJ Smiley,playing some kinda track

I thought it was "that's funny..."
