Hexagrin
Teodora is too common, Teodora Angelova is too long and I don't have a high school nickname. That's why I had to come up with an alias to use around the web.
After some brainstorming I chose Hex(a) cause it means a lot of cool things and simply added a broad smile - grin.
Hexagrin is short, always free and serves me well. Try this Google Search
