Add this misinterpretation to protocoldroids's list:

one of the most commonly misinterpreted rock lyrics in the last century. the actual lyric is "revved up like a duece, another runner in the night", but it really sounds like "wrapped up like a douche", the song is "Blinded by the Light" by Bruce Springsteen.

the lyric is also commonly mistaken as:

Wrapped up like a douche, another runner in the night

Wrapped up like a douche, another rubber in the night

Wrapped up like a douche, you know the ruler in the night

Wrapped up like a douche, in the middle of the night

Wrapped up like a douche, another boner in the night

Wrapped up like a douche, an utter rotor in the night

wrapped up like a douche, you know the rotor in the night

wrapped up like a douche, another rumor in the night

Wrapped up like a douche, a little odor in the night

Wrapped up like a douche, a bad odor in the night.

Wrapped up like a douche, and a stoner in the night

Wrapped up like a douche, spitting in the night

Wrapped up like a douche, another mother in the night

Wrapped up like a douche, you know a runnin' in the night

Wrapped up like a douchebag, for the Roman in the night

Revved up like a douche, another loaner in the night

Racked up like a douche, ya gonna run around the night

Washed up like a douche, breaking a rubber in the night

Revved up like a douche and turned her over in the night

Ripped off like a douche, another owner in the night

cracked...

as mentioned previously, it is one of the most commonly mishear lyrics. However, the song which this is misheard in is Mansfred Mann's version. It sounds exactly like douche even when you learn that it is deuce though. Bruce Springsteen originally wrote the song as "cut loose like a deuce..." and sang it saying deuce not douche.

One who is ridiculously preoccupied with trivial matters and therefore cannot be bothered with meaningful information from other, less douchey people.
