Bundasliga

A large group of females with big bums in the vicinity. 'Bunda' is slang for a big bum and the 'Bundesliga' is a German football league. Combining multiple bundas with the group aspect of football, that area has now turned into the 'bundasliga'.

Come to the party man, it's bundasliga in here.

I walked inside of the rave, fam, it looked like the bundasliga.

I think we should hit the party, I heard it's bundasliga in there.
