Hey all you friends fans. I was just wondering if anyone could tell me why the friends characters ocassionally hit their forearms together. What episode did that start in? Please help!!!

If I remeber correctly, it's a way of giving the middle finger without actually giving the finger. I think that's how Monica explained it because Ross had actually started it first when he did it to Rachel.

Hello Felicitylen,

Thanks for the info. Would you happen to know what episode that happened in, I mean when moica explains it to Rachel? Thanks again.

It started in The One With Joey's New Girlfriend (405).
