To say something is going to be a kick, does mean it will be fun (or at least entertaining to some extent). It’s a fairly old expression and I think it’s lost a lot of its usage but you’ll still hear it from time to time. It frequently, but doesn’t have to, appear as “get a kick OUT OF” something. Still, your sentence is okay. I’ve never heard of S’mores, so I wouldn’t worry about that one much (and I’m a 59 year old US native English speaking lawyer). So, I guess Amy’s right (see, vocabulary is so endless you never stop learning new words). “Wasted” is just under the influence of some drug, which could include alcohol. I recall as a teenager hearing “stoned” all the time (back in the 70s), but that word has fallen into disuse. And, people always would be quick to correct me and say “stoned” didn’t mean drunk with alcohol, but high on some drug. Language changes rapidly so you have to keep an eye on things.

1) I've never heard "kick" used in this manner, but here it means "it will be fun." S'mores is a very specific dessert made of graham cracker, melted chocolate and toasted marshmallow. It is almost always made over a fire while camping, but there are some products sold in the store that have the same ingredients and are "s'more flavored." 2) Under the influence, not sober. Usually it means you have taken drugs, but it can also be used if you are very drunk (after drinking alcohol.)
