blit /blit/ /vt./ 1. 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. 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.)
