A group of two who think they’re the only ones who matter.

My cousins are a couple of Legos. They think the whole world revolves around them.

My parents said, 'You and your brother are the best couple of Legos we’ve ever had.'

My friend’s mom said, 'You and your boyfriend are a couple of Legos. Don’t forget about me!'
