'Psycho' is an understatement
Krieg, Borderlands 2's newest downloadable character, has some sort of odd affliction. Somewhere between his brain and his mouth, his intended words get replaced by phrases of utter insanity. At least he lives up to his namesake of "Psycho".
This is how we come to learn that Krieg has the shiniest meat bicycle. It's also how we find out that he's the conductor of the poop train. Sadly, it's never established if this fecal locomotive is figurative or literal.
I hope it's literal.
