mee-maw

mee-maw

To exaggerate the movements of one's face, mouth, and lips while speaking so as to be understood from a distance or in the midst of a loud noise. Primarily heard in UK. I was trying to mee-maw at Jim from across the room to turn down the music, but he didn't get what I was trying to say. We've all started mee-mawing during work because the noise from the machinery makes it too loud to speak normally.
