1 definition by WaterBBgirly

A person who feels free in the water. Sometimes you may be sick with a headache or light stomach ache. Hop in the shower and you'll feel better.

Another great example of a water baby would be Percy Jackson from the movie "Percy Jackson and the Olympians". Percy says that whenever he is in the water, he can think more clearly on things.
"I had a terrible cramp this morning, so I took a shower. Wow, did I feel GREAT afterwards! It's good to be a water baby."

"That Percy Jackson character is a total water baby version of Zac Effron."
