During a recent interview with Lucha Libre Online, Vickie Guerrero revealed the origins of her popular catchphrase, "EXCUSE ME!" 

"When I went out to the stage and [Edge] pushed me on the wheelchair, I went out there and I’m like, I just even know where to start and I even know which promo out to grab. I was lost. So the crowd is very smart, the fans you have to give them credit because they know exactly what’s going on in my face, (my) expression. I forgot and they started saying things like you need to go home. You don’t know what you’re doing. Get off the stage. You forgot your lines and I just yelled: ‘EXCUSE ME’. I said it again and then I didn’t think anything of it and then the next week, the writers are like, hey, let’s try that. Excuse Me again. Little by little the fans were expecting it every time I would come out for my promo or whatever I had to say."
