Well in the 50s wives used to call their husbands 'daddy' as a term of endearment, just like how now some people call their girlfriends/boyfriends 'baby'.
My grandma called my grandpa "grandpa" and my mom called my dad "daddy" when I was little, because that's how (grand)parents refer to each other in front of their (grand)children, right? But in any other situation I find it creepy.
The one she's wearing isn't one but I have seen idiots wear bdsm toys meant to keep your mouth open while someone rams their cock down your throat as chokers
