I use like, was like, was all, totally, Seriously? and Really? (in the are you effing kidding me with that sense), and for a while I could not agree with someone without saying, "I know, right?" but I've more or less stopped that. (And I picked that up here, which is weird... like, I translated it into spoken word, and then started using it. Freak).
But I don't use literally as an intensifier.
God, if my niece uses "legit" any more than she does right now, it will, heh, literally be in every sentence she utters. That's the only one that grates on my nerves at the moment.
I love shortened words, too. The first time I saw "totes," it was love. (Pretty sure it was bon bon here.)
