да ну его! – English translation

let shit go (Дисфемизм от "let it go". Vadim Rouminsky)

screw it! (I figure, how am I gonna report this? They'll think I'm crazy or something, I mean, how the hell do you report this type of stuff? They wouldn't take me seriously. I said screw it, and kept driving. There wasn't any damage on the truck or anything so whatever.
