A nickname used between people who are so in love with one another, that no one else understands. To be someone's Abbe is a great compliment. And it's even funnier because no one else knows what the hell Abbe means, and those that do know don't give a fujk!
Bryce, you're my Abbe. I love you more than anything else in the world, and I don't give a fujk about what anyone else thinks!
