To an outsider without the explanation of "MV", he / she may wonder what it is. Also, if you are to use just "MV", I would say the second word has to be strong, to support its appeal
Example:
M/V R/I/G - Not really
M/V B/I/N - Not really
M/V K/I/L/L - Not really
M/V W/O/R/L/D - Acceptable
M/V G/A/M/E - Acceptable
M/V M/U/S/I/C - Acceptable
IMO
