What does "Roll One Deep" mean?

Okay, guys!

Admittedly I belong to an older generation; there are some words and phrases uttered by the "texting generation" of which I am utterly clueless. Here is one: "Roll One Deep."
I came across this phrase from one of the questions posted by a teenager; I wanted to respond to it but was stymied by her jargon-heavy post. Is it slang? Thanks for aiding me in enlarging my personal dictionary.

Sounds close to "roll one down" meaning a condom...

Are you a "wicked" Uncle?
