Getting addicted to looking at/ sending e-mails, letting several hours go by being oblivious to everything but your own e-mail world.
Person A: I thought we were going to hang out 2 hours ago...
Person B: I know....I got stuck in an e-mail coma/loop, forgetting about the time. Sorry. I had a never ending circle of e-mails to read. I haven't checked my e-mail in a month, resulting in 1,356 unread e-mails...I totally forgot about it...Sorry!!
Person A: Oh I see...ya that happens to me all the time..Anyway, How about hanging out tommorow?
