WHOSAYONTHEWHATNOW?

Expression of extreme exasperation--and I mean extreme, people. Example: B. Hey, Amy, what did you do today? Amy, lying through her teeth as usual, Well, I parachuted out of a giant doughnut, ate some sugar-coverd lice, joined a circus, got engaged, died my hair upchuck green, developed three mental conditions, and fell in love with a goat. B. Whosayonthwhatnow?
