Okay, I know what it means, but I'm not sure how well I can describe it...here we go:
After you chain 2, put the hook through the chain at the opposite end (which isn't far since it is only 2 chains). Loop the yarn around the hook and bring it right through both the far end chain and the one that was already on the hook (that's your sl st: slip stitch). Check following link for pictures/videoshttp://www.stitchguide.com/stitches/crochet/stitch_pages/cro_slip_stitch.html
Now, count to the second chain from where your hook is and do 6 single crochets all in that same stitch. After that, do 2 single crochets in each of the 6 stitchs you just made. (you will be going around in a circle at this point)
However, I have seen patterns that do this instead (which I prefer):
Chain 2 (though I prefer 3 for size of circle) and do the slip stitch.
Now (as opposed to the original directions that require putting many stitches into a single stitch), make 6 single crochets into the hole within the circle (that you made by slip stitching your chain together...not into any stitches). Then do 2 single crochets into each of the 6 stitches you just made (again, you're going in a circle at this point.
For some reason, some patterns call for you to create a bunch of stitches inside 1 when it seems much sturdier to make them within the center of the circle you created....
Anyway, I hope this helps.
