My closest friends and I go together to bingo in various local areas. Another group of gals from our area have been playing bingo together for years and they wear cute shirts that say "Bingo Babes".
We get along very well with the other group, and sometimes share rides, and we told them we are going to get shirts too. But we can't come up with a name we like.
Someone suggested "Bingo Beauties", and we have thought maybe "We win at Bingo" (we do!), or "Seniors Do It At Bingo".
