One of the cutest girls to have ever existed. Full of love, kindness, and abounding amounts of talent. Tatum will always knock you off your feet with a good joke or with their absolute sheer amount of pure cuteness.
“Wow man I met a girl named Tatum yesterday, she’s literally the cutest cutie ever!”
“You make me so happy Tatum, you’re the best friend someone could ask for.”

The quality and nature of (the) being Channing Tatum, consisting of supreme flawlessness, immaculate beauty, powerful grace, and sheer hotness and total eye candy; what is on the right hand side of Jesus himself (for even Jesus cannot resist this force).
His Tatumness appeared in 22 Jump Street and I basically died.
