My best friend & I have quite a few.
"Uno Mas" is one of them.
So is this one phrase we heard while flipping through channels...
"Why do you always have to have a corn dog in your hand when I go to give you a high five??! You make me look like a q-hole!"
we also have
"That's your boyfriend." It's actually a game we play whenever we are out in public, whether it's school or the grocery store.
& there is a crap load more.
