Or get a brake if you're not skilled enough to ride brakeless.
That annoys me. Any muppet can ride sans-brakes. To do it and not suffer injury (or inflict, eh Mr. 50:14) is what counts.
OP: As others say it's probably a loose cog and lock ring (you do have a lockring on right?). Put your bike away and wait for the brakes to turn up or at least take it very fscking easy.
