Cirumlocution? How do you describe yourself?

I've been pondering changing a variety of the terms used to describe several different client projects I am involved with and wanted to ask the question: How do you describe yourself?

As a "social media guy" my industry is cluttered by technical, marketing, and social terminology. I know other business folk here have like-minded problems. I often have to be very simple with statements "I help businesses online" or "I increase bottom line profits with online business development" I often hear a lot of people lose connection by using fancy terms or industry jargon.

For kicks, this is the most complex way I can describe what I do:

Cirumlocution: "autodidact social media bailiwick métier"

Circumlocution \sir-kuhm-loh-KYOO-shuhn\: The use of many words to express an idea that might be expressed by few; indirect or roundabout language.

Autodidact \aw-toh-DY-dakt\: One who is self-taught.

Bailiwick \BAY-luh-wik\: A person's specific area of knowledge, authority, interest, skill, or work.

Metier \met-YAY; MET-yay\: An area in which one excels; an occupation for which one is especially well suited.

How do you best describe yourself without being lost in technical jargon? Do they even know the words you are using?
