we dont want people clinking glasses, so what can we do?

Question

my fiance and i are planning a very rock and roll themed wedding. blacks and reds, and well, rather goth and roll looking...we go to a lot of concerts, and this is just our style, so were trying to carry it throughout the wedding.

the thing is though, we really dont want people clinking glasses. it drives everyone nuts. where i live, i dont really have to worry about it getting out of hand, even at weddings where clinking is allowed, it never goes overboard.

so, what can we have guests do that is a little rock and roll flavored? nothing to complicated please! i know lots of ideas for replacing the clinking with something else, but nothing really that seems very..idk, rock and roll.

lol, dude i almost just died laughing when i pictured my guests smashing guitars! omg thats fun! unfortunatly we cant afford the guitars, or the clean up bill for smashing them. good job though dude, you definatly made me smile!

i like the air guitar idea, the grooms dad would really get into that. like, we plan on having very rock and roll music playing all night, so people could just rock out to whatevers on. good ideas folks, keep em coming please!

lol, i hate how we have all the major stuff naild down for what we want but all the itty bitty details like this, we are clueless
