Sorry to break it to the people who basically created this theory, but it's just Mabel's name backwards. That's it. Yes, I'm sure it was intentional on the animators' part, but honestly, I think they were just having some fun in the studio and wrote that down just as a little joke.

Of course, the "super extreme major expert theorists!!11" of Gravity Falls fandom have got to go and belly flop onto this little joke and make a mountain out of a mole hill, or however the saying goes.
