Contrary to popular belief, gank has TWO meanings, as it is an incredibly versatile and handy word to have in one's lexicon. The definitions are as follows:
Definition one: something strange, and wrong, for example, a ganked tooth.
Definition two: something to celebrate about, for example, some gank results.
"Man, I just stepped on Edgar the hedgehog's ganked quill!"
"I've got some gank news, Daisy! We're going to Paris!!!"
