Couldn't tell you because I don't know what "dumbing her" means. My only guess is that, since "dumb" originally meant "silent or unable to speak" you mean that he is making her shut up. I dont know how that really works with your question, however.

It means that the person who is called smarty pants either does know or think she knows everything. It is not really a compliment, but then again, the person who is saying it is probably joking. People use the word pants instead of ass, which is definitely NOT a compliment.

"You're not ugly or stupid."\n\nI was really thinking... You're both, you goddamn loser without any self-esteem.

Both are holes.  I don't think it comes from anywhere.  It's supposed to indicate that a person is stupid.  They don't know one hole from the other.

It's kind of an insult in french. More like an exclamation insult, like "what the hell" in english. Something similar (not a traduction tho).

Why or not why? That is the question? No seriously, why what? Why is this question dumb.... Why are you being stupid? Why is this not even a question?
