We got in trouble with "Not Functioning Good" at IBM but we all swore that was what it meant.
Nobody believed us. Old VN era vets had lots of stuff that our elders were not comfortable with like "FKNA" for an affirmative answer to almost anything you were adament about. We may have invented most of the shorthand Emailers and testers use today. We had a Motorola RF text terminal in 1985 that we carried around.
The basic text message was 55 bytes max so you got creative.
