geekasm

Originally from a quote on the PBS show Scientific American Frontiers (week of May 21st 2002) by MIT professor Alex Slocum:

When they build a machine, if they do the calculations right, the machine works and you get this intense ... uhh ... just like a geekasm, from knowing that what you created in your mind and on the computer is actually doing what you told it to do

. Unsurprisingly, this usage went live on the Web almost instantly. Every hacker knows this feeling. Compare earlier progasm.
