An exclamation used to indicate when one has tried to be witty but has failed horribly (especially when intoxicated). Often used in those awkward silences after someone has tried to use a witicism among a group of friends. One may use "wampuh" against a friend or one may use it on themself upon realizing their failure at impressing others with what could have been scathing wit.
1. (origin)
girl: "It's hot in here. Dayumm."

guy: (two hours later) "Wow. I sent that thinking I would impress you (mind you, I'm stoned) but now I realize how moronic that sounded. Hah."

2:
girl1: "How are you feeling today?"
guy1: "Your mom."
girl2: "wow. Wampuh."
