A phrase that can be used to respond to many different styles of comments, mostly opinions. This word originally derived from early Euoropean fox hunters, who had at first been pompous and arrogant and thought the fox to be a stupid animal, only to be outwitted by the creature time and time again. So this saying is basically a disagreement stating "remember our mistake with the fox", or, "do not assume this is true".
An adverb, meaning "a lot" but it can be used in other contexts aswell. Cannot really describe it well but check out the examples and you should get it.
Used at the end of a sentence, usually when someone is in a circumstance that doesn't meet expectations. It has nothing to do with being gay, more about being sub-par.
Can be used as an insult directed at one's self, or as a joke directed at a friend.
"Yo bro, what's wrong?"
"I pulled a muscle in my back like a faggot."
