Top Definition
n. A spider's web; from 'atter' (poison) and 'coppe' (cup). Often used to refer to the spider itself (as from Norwegian "edderkopp", meaning spider).
Old fat spider spinning in a tree!
Old fat spider can't see me!
Attercop! Attercop!
Won't you stop,
Stop your spinning and look for me?
Old Tomnoddy, all big body,
Old Tomnoddy can't spy me!
Attercop! Attercop!
Down you drop!
You'll never catch me up your tree!
