In Rice University's theatre community, an adjective meaning bad. Comes from a play that the director kept referring to as "Brechtian," in reference to Bertolt Brecht's theory of street theatre as the purest form of theatre, but which resulted in an awful play. Has countless variations, e.g., "Just do it like Brecht" and "We're going to brecht it up."
If you do not remember your lines during the performance, we will have a very brechtian play on our hands.
