Because the phrase is short, it’s often pulled in two directions. One direction treats it as a literal-ish description: something “high, small, crawling/climbing.” That could describe stairs, obstacles, a posture, or a visual pattern. The other direction treats it as a label: a term someone coined for a character archetype, an inside joke, or a recurring online behavior.
Here’s how to separate those possibilities without guessing too hard. If the post includes physical details—angles, height, movement, equipment—or mentions places (buildings, stairs, ground, obstacles), you can lean literal. If the post is mostly emotional or judgmental (“this person,” “this type,” “what you’re doing”), you can lean label/slang.
None of this guarantees the meaning. What it does is give you a disciplined way to interpret a phrase that isn’t “self-defining” just because the individual characters are common.
