Comes from the common usage of the word MILF. This was then modified by the new wave of Sixth Formers as the mysterious cult known as the Brotherhood of Fist adopted it as their slogan. Means Ass I'd Like to Fist.

“Bro, she’s pretty hot after she had that kid.”
“Yeah but have you seen her sister Lucy? Total AILF.”

Similarly to MILF (Mom I'd Like to F**k), DILF (Dad I'd Like to F**k), PILF (Parent I'd Like to F**k), SPILF (Step-Parent I'd Like to F**k), SMILF (Step-Mom I'd Like to F**k), and SDILF (Step-Dad I'd Like to F**k), AILF stands for Aunt I'd Like to F**k, which obviously brings up the potential UILF (Uncle I'd Like to F**k), which you can type a definition for if you're really that desperate.
"Damn bro, that AILF over there's really a sexy one, isn't she?~"
