From http://catb.org/~esr/jargon/html/G/gweep.html: gweep: /gweep/ 1. v. To hack, usually at night. At WPI, from 1975 onwards, one who gweeped could often be found at the College Computing Center punching cards or crashing the PDP-10 or, later, the DEC-20. A correspondent who was there at the time opines that the term was originally onomatopoetic, describing the keyclick sound of the Datapoint terminals long connected to the PDP-10; others allege that �gweep� was the sound of the Datapoint's bell (compare feep). The term has survived the demise of those technologies, however, and was still alive in early 1999. �I'm going to go gweep for a while. See you in the morning.� �I gweep from 8 PM till 3 AM during the week.�
