Firm handshakes are fine and all, but to me it can be a little too uptight and formal in some settings. If I meet someone at a party or something, haha I'm not gonna shake their hand like I would at a job interview. Just a nice little waddup slap some skin or pound it whatever and move on.

Call me crazy, but I always kind of look twice at the people that give me a regular ole' handshake. It just doesn't look natural, or it looks funny, I'm not sure. ~
