Choboroo is from the Korean cho (초 — beginning, fresh) + boroo (보루 — defense, foothold). Choboroo is one of the Korean K-pop debut-era stage names — referring to the choboroo (first-line, foothold) concept of new K-pop trainees + debut groups.
Choboroo does not currently appear in the US Social Security Administration's top 1,000 girls' names, so we don't publish a US rank or birth count for it. That says nothing about the name's standing elsewhere in the world — only that it sits outside the ranked US data we rely on.

In Pythagorean numerology the letters of Choboroo reduce to 1, The Leader. This is a traditional interpretive system, not a factual claim about the name.
