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?~"
