OTC is a place where we can buy/sell bitcoins "over the counter". The Web-of-Trust (WoT) is a system used by OTC to rate and give reputation to buyers and sellers. Negative reputation means not very trustworthy, and more positive means more trustworthy (to a degree, since a lot of positive raters could themselves be negatively rated, so you got to check a bit more before trusting).
This explains in details.
