* In short, this trope applies if said mother is ''meant'' to be considered sexy ''in-universe'', that is, to the other characters. She does not have to be attractive to standards possessed by real [[PettingZooPeople humans]] with [[TheSimpsons normal skin tones]], and bear in mind that a [[SuspiciouslySpecificDenial troper entering an example does not mean he/she finds her attractive]], but is reasoning that she could be in-universe, or to certain groups within the audience. The trope does not apply just because you happen to find the character attractive, and, again, nor are people entering examples for that reason - go to the relevant [[FetishFuel pages]] for that! As mentioned, this ''definitely'' applies to the Western Animation section.
* Note that it will depend on a whole plethora of factors. Some of the candidates will make you [[FridgeHorror wonder]] just what the [[AuthorAppeal author or artist]] [[FetishFuel was thinking]], and why [[{{Squick}} anybody]] would fancy that character. And ''especially'' with regards to Western Animation, it may even vary depending on whether or not you consider yourself part of [[FurryFandom certain groups]], for [[FunnyAnimal obvious]] [[PettingZooPeople reasons]].
