What is Eilsoe?
1.
widely used term in nerdy societies. Usually seen in conjunction with removal of software, IE: "Pull an eilsoe", would be something in the lines of: "Re-format main drive".
Rumour has it, that a danish guy is behind this term.
"COPY dammit! Don't make me pull an eilsoe up your lower disks!!"
or...
"Hey hun, I think it's time to pull an eilsoe on the PC, it's acting up again...!"
