"Twin-fit" is a slang used in the Timeless Space that refers to a violent mob-riot caused out of desperation, and it has a rather dark origin.
The origin of the slang tells the story of twin time travelers, Hank and Jeff Pimbo, become lost in the Timeless Space and eventually find themselves in a pulp where the hungry costumers united to seize and ate them up. The consequences of this course of actions also originated the slangs Twin pudding (used to refer to a dinner that's regretfully served in a pirate pub) and Twin-craps (used to refer to dice games, whose origin is likely linked to the indigestion that the remorseful people felt after devour the Pimbos).[1]
