Japanese translation

I'm reading some raws. I'm hoping SOMEONE in here knows Japanese at a good enough level to help a bro out here.

What the fuck do these lines mean?
１．あくまでも目安にすぎん馬鹿が！
２．完全に間隙を突いたのに動揺しない！？
３．てこずらせやがって！

Thanks /lang/.

There is already a thread for Japanese questions.  You shouldn't have made this thread.
