Sleaze is one of the toughest things to accurately index as it is often far subtler than a life-changing event such as death. We tend to err on the side of caution: if we're going back and forth on whether something is sleazy, it probably should be classified as such. In this particular scene, we watch someone swimming and then emerging from a pool, backside to us. Since the whole "emerging from a pool" has been sleazed up in numerous other films (and commercials), we're slightly justified in saying that was a goal here. On the other hand, we don't classify background sunbathers as sleaze: they're not "doing anything", the camera isn't lingering lecherously, and there's no cues from other characters that we should be as lascivious as they are.
Sometimes it's hard to tell whether hard nipples are happenstance or intended. Doesn't much matter for the index though.
"Death by snowman" given that Jack's carrot nose was the catalyst, we hear him say "One down, one to gooOoO", and we find out (later) that he can turn into water. It's also hard to believe this guy would have drowned so quickly just by being thrown overboard.
I seem to remember other tong-related injuries, so let's first-class it, eh?
"Sleaze by mouth" covers the potentially arousing use of tongues and lips (slow applying of lipstick and blotting, chewmoaning an ice cube, etc.) without requiring separate categories (though "sleaze by lipstick" and "sleaze by kissing" are valid too). "Sleaze by noise" is a more generic form of "sleaze by dirty talk" and handles unintelligible sound like moans or screams.
