Obnoxnox
A person who is so loud and pushy, they make everyone else feel like the background noise.
My brother is obnoxnox. He yells so loud at the TV, I can't hear my music.
My friend is obnoxnox. He talks over everyone in the group chat like he's the only one who matters.
My dad is obnoxnox. He shouts at the radio like it owes him money.
