Spotted around 80 of these shots, it's about time to actually tag them - and I wanted to confirm the main tag name to be used + aliases beforehand.
Basically, these are cases where our point of view is split half above the surface, and half underwater.

Examples: post #185348, post #484219, post #675985
Main tag should be: over/under_shot.
Seems to be the most prevalent on web search results.
Aliases: over-under_shot, over_under_shot, /ous.
Not supporting for split_image and split_shot.
Rather vague and could confuse with split_screen.
Waiting patiently for your lovely replies before rolling the batch!
