"Urusai!! ... itten-dayo?!" - "Shut up!! Who do you think you're talking to?!"
"De..." - Slang that often begins a colloquial sentance, roughly equivelant to "So..."
"Kuso!" - "Shit!"
Foreign language text left untranslated in the strip will almost always have no real bearing on the content, but I suppose it's only polite to provide SOME translation.
