When a friend shares with you (what he considers) sound advice, a fun activity, or deal. However, the end result turns out to be the exact opposite.
Friend: "Let's go to this expensive restaurant where there's a special right now. I have a coupon and it will only cost you $50 each!"
End result from friend: "I couldn't find the coupon, but let's order this expensive wine. What? The deal is over? Oh, looks like it's going to be $150 each. Isn't this awesome!!"
Everyone else: "Shit! We just got Fycked!!!!"
