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.

Threadstalker 

Someone who follows another from thread to thread...usually with the intent to harm them by defaming their character, putting them down, continuing an on-going argument from a previous thread of several years past...etc.

hey, remember me...remember that time you said I didn't know what I was talking about? Yeah, you...you started it you Threadstalker ....you dissed me last month....so I am going to follow you and make your life miserable tell the end of your days. Or at least as long as it takes you to get a different on-line user name...And then I'll still recognize your sorry ass...and hound it.....
