so... I'm going to try this again. Originally I posted this in the "Etiquette" board (which I think there are A LOT of brides who don't quite understand what etiquette is because there are tons of posts that have nothing to do with it...). I got lots of responses, almost all of which were extremely rudely put. So I thought, since sometimes these etiquette issues are sometimes regional, and differ on say the east coast vs. the west coast or even Seattle vs. LA... so to cover my bases, I'll repost here in Idaho and see what you all think, and not let my FI see the responses, his sweet little feeling got hurt.

My FI and I started a what we're calling the "Money Hoon Jar". We got a glass jar, decorated it all cute and slit a hole in the top. When we cuss, we owe the jar a quarter. Then all the money in our Money Hoon jar we will use as play money on our honey moon.
This morning my FI had the idea to bring it to the reception and tell our guests it's something we're putting towards the honeymoon and if they want they could contribute too. we would do this along with or in place of a "money dance" or something.
I'm worried it may come off as "tacky".
Advice is welcome. Yay or Nay?
