Have you ever referred to someone as your twin, even though you're not related? Best friends do it all the time. Calling someone your twin is a way of saying you're connected on a deeper level than a normal set of friends.
Usually, this term is used by adults. But these "twin" girls have adopted the term into their own lives, and they're not about to give that up because of some haters.
Zuri Copeland and Jia Sarnicola are best friends, or as they call it, twins. The 4-year-old girls may not look alike, but that doesn't make a difference to them.
“They’re both little Geminis,” Ashley Riggs Sarnicola, Jia's mom, said. “They have very strong personalities and are both super outgoing, well-spoken, intelligent, and not afraid to tell you what they want. They hit it off right away.”
"It is unbelievable. They connected very well immediately,” Valencia Copeland, Zuri's mom, told ABC News. “It was amazing how they’ve gelled together."
But not everyone totally understands these "twins" and their bond. At a birthday party recently, the girls encountered someone who wanted to call their bluff.
