jackjawing
A human who talks so much and so loud that they make your ears bleed and your jaw ache like it’s been kicked by a donkey.
'Your jaw is doing the work of a construction site and I’m the one getting the noise complaints.'
'You’re so loud I think you’re trying to deafen me and your jaw is just helping out.'
'You’re like a loudspeaker with a jaw that doesn’t know when to stop.'
