Call BS on GM: discard ALL cards in play

[jiken]

So, on this card, the directions say to discard all cards in play. This can be read a few different ways.

1- (the least fun) Discard all one-shots and monsters pertaining to the current battle only

2- (more literal) Discard all the cards you have in front of you. It's like dying, except that you keep your hand.

3- (the most literal, and also wildest) Discard all cards in front of everyone. The "table flipping" card.

I read it to mean option 3, but I would like a second opinion, as some people might hesitate to use it that way.

I saw other threads regarding the card, but none on this issue. Thanks for any input!
