Aliasing buldge → bulge
Link to alias

Reason:

Some people seem to have a hard time spelling bulge. Aliasing this tag would prevent future misspelling.

Alias denied, and instead cleaned up manually. There's a few reasons, but mostly because buldge was a mixture of crotch bulges (which is what we use the bulge tag exclusively for) and abdominal_bulge which is an entirely different type of bulge in an entirely separate location. So an alias would have created a lot of mistags for either place it was aliased to. (At a much higher ratio than the bulge tag already has to deal with). Secondly, an alias is sometimes the best thing to do for a common misspelling, but other times it's not worth it or would cause other issues. In this case, there were roughly only 15 images under there, and they were pretty split between the two different types of bulges in usage. It didn't seem to be used often enough or frequently enough to be worth invalidating with an alias to invalid_tag either though. So instead it was simply fixed manually.
