HLL: /H·L·L/, n.

[High-Level Language (as opposed to assembler)] Found primarily in email and news rather than speech. Rarely, the variants ‘VHLL’ and ‘MLL’ are found. VHLL stands for ‘Very-High-Level Language’ and is used to describe a bondage-and-discipline language that the speaker happens to like; Prolog and Backus's FP are often called VHLLs. ‘MLL’ stands for ‘Medium-Level Language’ and is sometimes used half-jokingly to describe C, alluding to its ‘structured-assembler’ image. See also languages of choice.
