Ya'll best be steppin'

"Step off." though far less intimating. Really should only be said as a joke, and only with a horrible ghetto accent and (in)appropriate head-bob + finger-wave combo.

"That is one skanky skirt, sister."
"Yo bitch ya'll best be steppin'."

y'all, this is gonna be the best 

a phrase commonly used by a petite, bottle blonde, Southern girl who is overly excited, usually signified by the trademark pearl necklace, Lilly Pulitzer outfit, and inappropriate shoes

I hate those girls who get all excited about something ridiculous like the Junior League and exclaim to their friends that, "Y'all, this is gonna be the best!" in that annoying Southern accent.

You can't be the best

Correct. The slot has already been filled. There's one spot available and, like, I am the guy so...

Hym "He's right! You can't be the best. I am already that... Forever... And even if I had never existed... The fact that I COULD HAVE theoretically exist and would have been better means that I'm still theoretically better than you would be in my absence... So, Yeah... Both physically and theoretically impossible."
