Does this have a figurative meaning, like telling someone that they are 'collectors', or even 'hoarding' ?
Nope, just a silly sentence :)
Reminds me of Einhörnchen...who else had memorized 'Einhörnchen' from the response to 'Germans try to say the word 'squirrel'' video?
"Eichhörnchen" they are called. It must come from "der Eiche" (tree) or "der Eichel" (fruit of this tree or the tip of the penis because it looks a little bit like this fruit)
But it's "die Eiche" and "die Eichel" (feminine).
Yes, this is definitely a cognate of "Eichhorn" resp. the more often used diminutive "Eichhörnchen".
Danish "eg" = English "oak" = German "Eiche".
It reminds me, a german person, of "Eckern" or more precise "Bucheckern", the fruit of a beech.
