Khloe Kardashian -- Assaults Dance Floor With Blunt Object

Let's be blunt ... like Khloe Kardashian.

Khloe appears to have been blazin' at Tru nightclub -- where she partied Monday night with The Game and mom Kris Jenner.

Khloe was twerking up a sweat and apparently needed something to calm down ... at least that's the way it seems.

We've reached out to Tru ... for a reaction. So far, no response.

One thing's undeniable ... Khloe's smokin'.

Khloe says she did not inhale ... weed. She tweeted it was a hookah pen. Now you know.

Big difference between a hookah stick and weed.... #DumbDumbs
