To be unable to tolerate, accept, enjoy, or endure someone or something; to severely dislike or be thoroughly repelled by someone or something. I know I couldn't stand the sight of that horrible receptionist every day if I were to work here. He's just so mean and unpleasant! I can't stand the sight of my mother-in-law, but there are a few occasions each year where I can't avoid having to meet her. I absolutely cannot stand the sight of shellfish. Just being near it is enough to make me gag!
