Before I listened to this episode, my first thought was "oh boy, another episode about how every children's media trope spawned a fetish," but I guess this is actually a childhood-trauma fetish instead? Unless a bunch of these guys just got into it from cartoons and made up stories about their meemaw gagging them while she watched her stories, which frankly seems pretty plausible for these guys.
Anyway, I'm definitely picturing all the women described in this episode as anthropomorphic fiddler crabs, with one big ol' smotherin' hand and one regular fine-manipulatin' hand.
