, The dyke knows your girl has a problem with her sexuality, as the phrase your girl used to desribe her 'this lesbian bytch' suggests she isn't on friendly terms with her ,so the dyke farted in her face. I used to work in offices, people would 'crop dust' people they disliked.
Despite what porn, and the gay agenda wants to push, not all women are cool with dykes,your girl probably freezes her out ,the dyke isn't happy and she is probably laughing with her girlfriend, about what she did to that 'stuck up bytch' today. .
Iam sorry to disappoint people thinking this is some kind of mating ritual, releasing your colon around people you want to get into bed doesn't tend to work....
