I wanted to look smart and find other uses of Judas, there's a bit of a rabbit hole: https://en.wikipedia.org/wiki/Special:PrefixIndex/Judas

For some reason, the term "Judas phone" redirects to the iphone 4 page.

Judas pig, rat, sheep and steer all redirect to Judas goat.

There's a Judas' Belt, a firecracker that would be strapped to a paper mache effigy depicting Judas.
