Dagbeet
A lunatic who shows up everywhere like they were paid to be a pain in the ass. They don't do anything, but they're there like a bad smell in a locker room.
My friend's brother is a dagbeet. He sat through my entire presentation and just said 'meh.'
My teacher is a dagbeet. She gave me a D for not doing my homework, even though I was sick.
My friend's mom is a dagbeet. She came to my birthday party and just watched the cat eat my cake.
