"Main bitch" is term usually used by males to describe their number one, the girl who's potentially "relationship material." But on Mila J's new song "My Main" (just the clean version for now), the singer uses the term to represent her best friend, the one who will always hold her down -- her "ride or die" if you will.
Y'all feel this one or nah?
Through the ups and the downs, unconditional
I eat it in the morning like cereal
Here we go, here we go, we ain't done yet
When she call me Big Daddy, yeah I love that
