Yod is essentially a load of wank, which certain people have tried to introduce in the place of bare, meaning lots. It appears it is not as broad-reaching as bare though and refers primarily to people. Fortunately this word is unlikely to make it into general circulation as bare is actually far more practical.
For example, if one were to say "Yod is here", it would mean lots of people are here.
