(Edited to add: "Sloppy" kisses probably means an overly theatrical kiss. Sort of like slobbering and making loud smacking sounds with the lips while kissing passionately.)
I can see that the rest of wedding arc is going to end up in the Ruining the Glorious Moment pool at the rate things are going...
What's you gonna do when your friend is mental? SHORYUKEN What's you gonna do when she shout "GO KISS"? SHORYUKEN What's you gonna do when Marisa's fullscreen, spamming Master Spark to stop you from grazing? SHORYUKEN So S-Rank, so S-Rank, damn Reimu is so S-Rank.
I'm getting the impression that the real-life people Marisa and Reimu are standing in for are husband and wife, respectively, from the way they have been acting in this arc.
... They kind of act like Ran and Yukari did, as well...
Sloppy Shoryuken is the touhou version of Shinku Shoryuken.
