The peculiarity of Malbolge is that it was designed to be the worst possible programming language

Haha. Two choice quotes about the language:

Malbolge was so difficult to understand when it arrived that it took two years for the first Malbolge program to appear. The program was not even written by a human being: it was generated by a beam search algorithm designed by Andrew Cooke and implemented in Lisp.

and

Malbolge's probably biggest piece of evilness comes from the encryption of instructions as they are executed. That encryption, fortunately, has a few weaknesses that make writing Malbolge programs feasible.

The cryptanalysis of Malbolge is pretty impressive. At the end he even suggests some changes that would make the language even more difficult.

Way better than lolcode :)
