No Chitown, it's not just about meat. Lent is a symbolic rememberence of the 40 day fast that, according to the Bible, Jesus did while he was in the wilderness. Many Christians take this period of time to fast (or give up) something as a symbol. Traditionally, many Catholics abstain from meat on Fridays. I'm a Protestant, so my past fasts have included candy, red meat, liquor (very difficult that year ;)), cussing, etc. It's completely up to the person.
