I'm trying to find a video that frequently made its rounds on various 4chan boards back in like 2009-2010. Its a clip of an anime (looks like late 90's), and this guy in a WW era uniform meets this girl in a tunnel to try and smuggle her to a train (or something), and during the dialogue he immediately goes from zero to 100 and says something to the effect of "if i see you here again im going to throw you on the ground and rape you!" and then the girl says "thank you". Its hilarious because the dialogue is just so clunky. Ringing any bells?
yep it's called Orguss 02
