Hack-and-Slay

v. (also 'hack-and-slash') 1. To play a MUD or go mudding, especially with the intention of berserking for pleasure.

2. To undertake an all-night programming/hacking session, interspersed with stints of mudding as a change of pace. This term arose on the British academic network amongst students who worked nights and logged onto Essex University's MUDs during public-access hours (2 A.M. to 7 A.M.). Usually more mudding than work was done in these sessions.
