I say "yo" alot... I don't quite understand where I picked that up. I once twisted my ankle, fell and landed on my face (considerably gracefully) and when my friend helped me up I said, "Jeezum Pete, my face hurts yo." I also drop the F-bomb alot. Well, in my case it's more like an F-NUKE because when I say it I normally say it belligerently loud.
