what do they mean？
”I'm not a MILF, I'm not even a mum. I am a spinster, I'm a SPILF.” They are movie lines from Bridget Jones's Baby (2016). What do MILF and SPILF mean？ Are they abbreviations？
Thank you for all your help.

Answer

MILF is a derogatory acronym for a  very sexy woman who is  married and is  still very attractive to many men. The letters stand for (a) Mother I (would) Like (to) F***.

Answer

MILF is the acronym for Mother I would Like to Fuck, a spinster is an unmarried woman beyond the usual age of marriage, so SPILF is a joke, stating Spinster I would Like to Fuck. Pretty gross, but you asked! hehe
