A pejorative term for King's College London, generally used by students at its rival institution, University College London. The term manages to convey a sense of KCL's being mediocre in both academic and social terms: a polytechnic was, in the UK, a college offering mainly vocational degrees, widely considered to be inferior to the older universities, and with an attached social stigma. The Strand is the London street where 'Strand Poly' has its main campus (although it has spread to the South Bank and beyond.)

A portmanteau of carpe diem, a Latin phrase that means “Seize the Day!” and DM, which stands for Direct Messages. This word means seizing the day via DMs.
