Where the hell did you put my flathead screwdriver?!
Literal
My [possessive-の] flathead-screwdriver, where [to-に] did-put?!
やる here is the 'to put/place' sense (JMDict sense 3), not the common 'to do' — どこにやった = 'where did (you) put it.' 俺 marks this as rough masculine speech, someone angrily hunting for something they think has been misplaced. マイナスドライバー is a wasei-eigo compound literally 'minus driver,' named for the dash shape of the tip; contrast with プラスドライバー (Phillips-head, 'plus driver'). The object particle を is dropped entirely from マイナスドライバー — normal in emotive casual speech.
