/dī-nə-ˌsȯrs mātiŋ/
n. Said to occur when yet another big iron merger or buyout occurs; reflects a perception by hackers that these signal another stage in the long, slow dying of the {mainframe} industry. In its glory days of the 1960s, it was 'IBM and the Seven Dwarves': Burroughs, Control Data, General Electric, Honeywell, NCR, RCA, and Univac. RCA and GE sold out early, and it was 'IBM and the Bunch' (Burroughs, Univac, NCR, Control Data, and Honeywell) for a while.
