The way I recall it (from Tannenbaum's book on operating systems) is that 
MULTICS stood for MULTiplexed Information and Computing Service.  An associate 
of Dennis and Ken's at Bell Labs called their scaled down version UNICS, for 
UNiplexed Information and Computing Service.  This nameplay evolved into UNIX.
