MooMoo (무무) comes from shortening MAMAMOO: MA-MA-MOO becomes MU-MU (무무). It's also an onomatopoeia — "moo moo" like a cow — which fits MAMAMOO's fun, self-deprecating humor.
Who Are MooMoo?
MooMoos are known for their passionate appreciation of MAMAMOO's live vocal performances. They record and share fancam footage of member ad-libs and vocal moments with fervor. MooMoos are particularly strong in Southeast Asia and have built one of K-pop's most active fan-translator communities. They are famous for creating high-quality fan-made compilation videos of MAMAMOO's live stage moments.
MAMAMOO's lightstick is a purple-glowing star-shaped instrument — the "Whalien Bong" — styled after a musical note/whale combination. It syncs via Bluetooth. The color is MAMAMOO's signature purple.
