Threadstick

NOUN - An ocurrance whereby you find yourself STUCK to an EMAIL thread that clearly doesn't involve you. No matter how many times you try you just can't seem to get yourself removed.

Dear Harriet, can you please make your way down to the Home Depot, ask for Sammy in the Hand Tools dept and locate a Crow Bar to PRY MY SORRY ASS off this Email Thread. This Threadstick clearly doesn't involve me.
