gweep
/gweep/ To hack, usually at night, or one who does so. At WPI, from 1977 onward, gweeps could often be found at the College Computing Center punching cards or crashing the PDP-10 or, later, the DEC-20. The term has survived the demise of those technologies, however, and is still alive in late 1991. "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."
"Gweep" originated as an onomatopeiac term, evoking the sound of the (once-ubiquitous) Hazeltine 9000 terminals' bell on WPI campus.
