Attitude! When forming up a new organization a few years back, I ALMOST convinced my friends to name the team "Attitude". Perfect for 14U and 16U girls! My girls actually liked the name. We went with Xtreme, but I'd love to see a team named Attitude!
Funniest team name I ever saw was WNTG. When asked what it meant they had numerous answers. Funniest answer, the one I remember, was it stood for We're Not That Good. Actually they were pretty good for their area and level and had a lot of fun with the name.
We're the Maniacs - last year, the Curvy Crushers during regular season and the Sassy Stealers during All-Stars. Dirt Divas are a team we played last season - cute name. A competitive team (boys) in this area are called the Dirt Bags. It's gotten a lot of laughs!
