1.
paying too much for something, just because it's on a "bargain" shopping website; victimized by shifty puffery on a bargain shopping website (like groupon.com)

2.
Being lured out for a meal by a friend at a questionable establishment only because they have a Groupon (or like discount) that they need to spend.
My friend totally grouponed us last night. We went to this crappy restaurant just because he had a Groupon.
