Bub (Brainfuck Ugly Bodge) is a variant of Brainfuck designed by Matthew Westcott. The essential difference is that Brainfuck's "while"-like instructions are replaced by "GOTO"-like ones.
Bub's claim to fame is that there is an interpreter for it written in Muriel, as a means of showing that Muriel is Turing-complete.
