I was asking about where you got what you claimed I said which I didn't.
And no, the Karen I'm referring to was not overweight her whole life. She doesn't even admit to being overweight now, well at least not directly (her projection and ire give it away). She even did some 'modeling' back when she could.
"Old fat Karen," (as supposed to "fat old Karen") is referencing a song.
For those a couple of generations shy of Boomer-ville:
"Old black water, keep on rollin'
Mississippi moon, won't you keep on shinin' on me"
