Why do we call linear interpolation Lerp?

Based on this simple background, I guess it became well known to the population and settled down.
特に Especially the latter is my personal fantasy.

en.wikipedia.org says "In that field's jargon it is some times called aerp."
The above and en.wiktionary.org also did not mention the origin, and I did not know who or why I got this abbreviation right.

If you search "lerp" for a link destination, the source comments quote the 2003 Jargon File.

-- LERP
-- /lerp/,vi.,n.
--
-- Quasi-acronym for Linear Interpolation, used as a verb for
-- the operation. "Bresenham's algorithms incrementally between the
-- two endpoints of the line." (From Jargon File (4.4.4, 14 Aug 2003)

In the end, the answer was "At least since the beginning of this century, I have gained some understanding as an abbreviation for Linear Interpolate, but I couldn't find my first appearance or exact origin."
This was the limit of my ability to search, but I feel that this is the only content that hits Google.
