n. Hacker slang for the key combination that resets or reboots a computer or program (such as Ctrl-Alt-Delete, AKA the "three-fingered salute").
"Doh! Looks like Netscape is sucking mud again. Time for the old Vulcan nerve pinch."
This phrase originates from the original Star Trek series in which Mr. Spock (a Vulcan) would render foes unconscious with a casual neck pinch. Wondering about the phrase sucking mud? This is another colourful hackerism (it was the Daily Word back on September 22, 1996) and it refers to a crashed computer or program. According to the Jargon File, this phrase comes from the oilfield lament, "Shut 'er down, Ma, she's a-suckin' mud."
