The meme plays on the double meaning of Linux command names when strung together in a certain sequence. What looks like innocent terminal commands to a sysadmin (unzip, strip, touch, etc.) suddenly reads like a steamy romance novel when combined.
This is what happens after 15 years of managing servers - you start seeing innuendo in perfectly innocent bash commands. And they wonder why we prefer the command line to GUI interfaces...
Next time your non-tech friend asks what you do all day, just show them this command sequence. Either they'll never ask again or they'll suddenly want a career in Linux administration.
