LISTEN UP HERE IS A STORY
Ok, there's a game called Code of Princess. It's a good beat-em-up game that's not really super amazing, but it's fun, and the story is pretty funny. ^^ Now, the reason I'm writing about this is because one of the characters has a kissing based attack. I cannot, however, record it myself, since it's on the 3DS. I also imagine that it would be difficult to record for four reasons.
1. The game is a 3DSware game, it is only available on 3DS and needs to be downloaded from the eShop. EDIT: This point is null, there are physical copies too.
2. The character in question, Eluda, is only available in multiplayer versus modes, and take it from me, there is usually nobody playing online multiplayer.
3. Eluda is (along with regular Villagers) also a joke character, so the chance of finding someone that is her is pretty low.
4. Eluda's kiss-based attack just has her lean forwards and blow a kiss. It makes a heart projectile that is slow and doesn't have that much range at all. It may be my own personal opinion but it may just be more efficient to do melee combos.
If you have the means to get a video, go nuts, it'd be pretty cool.
