I called this short girl an oompa lompaa, she stormed off crying. What should I do?

I was with my mates and this girl tagged along as she shares the same mates too. Me and her don't see eye to eye. She kept scowling at me and throwing in comments and shaking her head when I was telling stories/banter with my mates. After a while (few drinks later) I started to get peeved and told her to keep out of it you oompa loompa. She stormed off. She blocked me on facebook, ignores my text and emails now.
