Irish Soairsa, a breath of Fresh air or what

[Forrest]

I think the original term MILF referred to the mother of a mate of yours that you would like to fuck, so that would generally put a MILF over the age of 35. Soairsa can, strictly speaking, be referred to as a MILF as she is a mother some of you would like to fuck.
Yummy Mummy or Young MILF are probably more accurate.
