The snarling motion of your lip when you hear some hard/emotional/unbelievable techno music.
The suprised look of awe when you hear something amazing for the fist time in a techno track.
The look you have when a DJ is hitting that button in your gut.
Oh my god look at his/her techno face.
Let me see your techno face.
This is my techno face.
