Does it mean anything when a guy calls you by the short version of your name?

And I don't mean common short forms (like Liz for Elizabeth). In this case, my name isn't Larissa but it's similar. The other day when he complimented me on something, he said "Good job, Lariss!"

Only my best friend calls me by that short version of my name...so I see it as personal.

I saw it as a way of being flirty, given that he has been flirty otherwise.
