when there is a female linesman often "get back to your kitchen"
when theres a marriage proposal on the pitch "you don't know what your doing" - not overly sexist but quite funny
"she fell over" and "get your t*ts out for the lads" are quite common at every club really
I will say though as a football fan myself very few of these songs/chants are meant to be offensive and not many are taken that badly either
