Cop – to grab, from Germanic roots to do with stealing or buying – is only said by a troll:

• 02.051 look what I’ve copped!” said William.

Please note that it’s a different root from “attercop“!

Update 2015.10.05 – or is it?  OED and Merriam Webster dictionary seem to be in conversation about whether a “cobweb” is a “grab-web” and which came first, “cobweb” or “cob”.  I’ll update you when I know more, Word Fans!
