The fan-given nickname for Motoaki Tanigo, who is the CEO of Cover Corporation: a talent agency that manages the virtual YouTuber group Hololive. It is pronounced "yah-goh" and is often written in all-caps.

YAGOO has become the butt of many inside jokes among fans after he claimed that Hololive was an idol group similar to AKB48, when in reality the group mostly consists of cute deranged psychos who smash desks, eat sand, and try to drink each other's piss.
