What happened to the brand?

I don’t know.

In an effort to “be nice” to the unknown BOTL here I fired up my Google machine and I don’t see squat.

Best I can do for you is recommend a Fat Bottom Betty.

Most likely answer is a Redwood City company that began in 1995 and was "featured" in an episode of Seinfeld (though the label was not apparently visible on screen). Couldn't find when the company ended though.

Less likely answer is a Don Carlos Santiago rolled cigars in pre-revolution Cuba that were fatter than the usual Cuban counterparts and known to his loyal fans as Big Butts.
