A kid or teen who gives off the mood that makes you think "he definitely has swimming lessons".
"Person 1: Hey, not to be mean, or doesn't that kid look like he does some type of sport?"
"Person 2: Oh, yeah, he does have some swim meets."
"Person 1: Thanks, I could tell that kid was a swimming kid or other kid who does a competitive sport."
When you cum in the bath you are taking.
I went swimming with the kids this morning and man was it awesome.
