cog/chain/lockring slipping while skidding
So my bike is a stock Motobecane Messenger. I got it installed at my lbs and its been perfect until recently. Last week i started riding brake-less and every once in a while i feel something slip while skidding or accelerating. I'm no expert so i am wondering is it safe to ride/what is it that feels like its slipping?

Lockring and cog is loose. Go back to lbs to see if threads are damaged. If not have them grease up and tighten it!

No, you should stop riding it. Go get your cog and lock ring tightened and pray you didn't damage/strip the threads.

Ride up a steep hill and then tighten your lockring. If it's not too late already.

Because you'll put a significant amount of torque on the cog, tightening it up. If you insist upon riding it(which you shouldn't), at least do that to tighten the cog and stop skidding and use your brake(s) until you get the lock ring tightened. But really, it'll take 3 minutes for your LBS to fix it(if your threads aren't screwed up).

Instead of riding up a hill I suggest rotafix method. That is how I install and remove all my cogs.

Find a different lbs that isn't incompetent for insufficiently tightening your cog / lockring in the first place.

I tightened a cog via rotafix once before, did a good job. Only resorted to that though because my **** kept slipping like yours and there's not a big hill nearby. I've only had to do that once, ever, though. invest in a 1/8 chainwhip and lockring tool, you'll be happy you did.

Good decision. Take responsibility for your equipment and it will take care of you.

I have a feeling that if someone owns left hand thread, oversized, small-pitch tap kit; they already know how to tighten their cog and lockring.
