Continuation in linguistical history of CBDT ("Can't be doin' that"): While it has enjoyed increased popularity at UMCP, its introduction into the University of Maryland colloquialism is thanks to the esteem efforts of University of Maryland, Baltimore County's High Cultural Emissary Sadif. For her work she is likely to receive the Nobel Peace Prize in Literature. It is usually performed in conjunction with a 'Cut that out'-esque motion to emphasize severity of how much you should really not be doing that.
