bitblt /bit'blit/ n.

[from [BLT], q.v.] 1. [common] Any of a family of closely related algorithms for moving and copying rectangles of bits between main and display memory on a bit-mapped device, or between two areas of either main or display memory (the requirement to do the [Right Thing] in the case of overlapping source and destination rectangles is what makes BitBlt tricky). 2. Synonym for [blit] or [BLT]. Both uses are borderline techspeak.
