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

  BLT /B-L-T/, /bl*t/ or (rarely) /belt/ n.,vt. Synonym for {blit}. This
     is the original form of {blit} and the ancestor of {bitblt}. It referred
     to any large bit-field copy or move operation (one resource-intensive
     memory-shuffling operation done on pre-paged versions of ITS, WAITS, and
     TOPS-10 was sardonically referred to as `The Big BLT'). The jargon usage
     has outlasted the {PDP-10} BLock Transfer instruction from which {BLT}
     derives; nowadays, the assembler mnemonic {BLT} almost always means
     `Branch if Less Than zero'.
