The re-uptake of
the pen you were just using into the
stratosphere (or so it seems); when the pen you had manages do disappear
without a trace from the face of the earth, to be found again long, long after you've given up (if ever)
"I was JUST writing
notes with that
pen, where the HELL did it manage to get to!?!?"
"Looks like you've just experienced pen evaporation,
brah."
