standing split

When a character is standing on one leg while the other leg is raised so high that it looks like the person is doing a vertical split.

Not to be confused for a high kick or axe kick.

In October 2020, the pose became a Twitter meme under the hashtag #I字バランス部. It originated with post #4129230 and post #4119640; see comment #2047996 for details.
