From Jargon File (4.3.1, 29 Jun 2001) [jargon]:

  blit /blit/ vt. 1. [common] To copy a large array of bits from one part
     of a computer's memory to another part, particularly when the memory is
     being used to determine what is shown on a display screen. "The storage
     allocator picks through the table and copies the good parts up into high
     memory, and then blits it all back down again." See {bitblt}, {BLT},
     {dd}, {cat}, {blast}, {snarf}. More generally, to perform some operation


     (such as toggling) on a large array of bits while moving them. 2.
     [historical, rare] Sometimes all-capitalized as `BLIT': an early
     experimental bit-mapped terminal designed by Rob Pike at Bell Labs,
     later commercialized as the AT&T 5620. (The folk etymology from `Bell
     Labs Intelligent Terminal' is incorrect. Its creators liked to claim
     that "Blit" stood for the Bacon, Lettuce, and Interactive Tomato.)
