What does it mean when your co-worker keeps touching your shoulder/arm?

I work with a girl and we joke most of them time so sometimes when I tease her or make a joke she like fist bumps my shoulder and sometimes she says "you're so ruuude" in a playful way when I tease her or something.

Does this mean she likes me more than. A friend or she is just being friendly.
