A$AP Rocky's Flossing and Nobody's Stopping Him

A$AP Rocky's not retreating in fear after the Kim K jewelry heist ... he's still proudly flossing.

The rapper was leaving Catch in WeHo Wednesday night when we asked about hooking up his homie, Lil Uzi, with advice after gifting him a $100k chain.

Check out the vid ... Rocky's definitely got some advice -- for would-be thieves out there.

Now that's purple swag.
