When you notice the "..." indication that someone is replying to a text -- and. it. goes. on. forever -- only to FINALLY arrive as an "ok" or something extremely brief given the amount of time you were "bubbled."
"Oh man, I was just text bubbled for, like, 15 minutes for a two-word reply. WTF?"
"After text bubbling me for five minutes, you reply, 'ok.' It took you that long to write, 'ok'?"
