EATDATBUT
A person who talks too much and no one listens because they're too dumb to shut up.
My brother talked for 10 minutes. I said, 'EATDATBUT, shut up before I throw you out.'
My teacher said, 'EATDATBUT, I can't hear the lesson because of you.'
My friend talked during my lunch. I said, 'EATDATBUT, I'm going to die of boredom.'
