When an event is built up to be one thing, positive, but turns out to be another, negative. The person being directly affected is usually left feeling like a chump. Much the way real Amway representatives get people pumped about "business opportunities" and turns out they just want someone to sell their shit.
I was completely Amwayed by Pat at the show the other night. He spent all last week hyping up this new band. Not only did he not show up, he never let me know he wasn't coming AND the band sucked!
