the byproduct of an electric razor or beard trimmer losing its battery power when one is only half way finished trimming their pubes. The finished product, where one half is neatly shaven and the other half is full of thick or coarse hair, looks like Harvey Dent's in the movie Batman after burning half of his face; gaining the appropriate name 'Two Face'
Guy # 1- "Dude, I was doing some 'manscaping' *trimming my pubes* and my electric razor battery died right when I had finished my left side. (Guy #1 then proceeds to show Guy # 2 his pubic region)
Guy #2- "Holy Shit! It looks like Harvey Dent after he became Two Face in Batman."
