A person who trains rigrously almost everyday to reach their athletic potential. Rarely aren't found eating. Stick with their own kind like peanut butter on a pinecone. Love cold water, and waking up a 5:00 in the morning to practice for two hours and thirty minutes and still go to school afterwards. They don't all have big penises and not all of them are tan, but they are one damn sexy human being. Swimmers also tend to look squishy despite the standard six-pack. This is because they spend almost every day saturated in water. Thus making their flesh automatically glisten. Shaving parties occur often.
