blit

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.)
