Nexoplause

You know that time when you think of the most hilarious, pee-your-pants, laugh-out-loud idea ever? Well, after a laughing fit, an algae bloom even you may go on to explain just what you've gotten so hyped up about. When it all comes together, at the punch-line perhaps, the audience is left in confusion of either- uh-huh? or anticipating something really funny is yet to be said. Either way a nexoplause is horribly embarrassing and should be avoided at all costs.
(often a reputation or ice-breaker catastrophe)
