The time in a newly-formed relationship where the couple is completely obsessed with eachother. The couple must spend every waking minute together and the only thing they talk about is how in love they are, how lucky they are to have found eachother etc, etc,. The new car smell usally consists of annoying texts to friends bragging about the relationship and posts on facebook that make everybody on that persons friends list want to puke and/or gouge their eyes out to spare them from the repetitive post about their "special, one of a kind love." The new car smell usually last the first few months of the relationship and on some rare ocassions can last a year or two. After the new car smell wears off the couple pull their heads out of their asses and realize that they are no more special than any other couple.
Anything that last longer than that isn't qualified as a 'new car smell', but rather said couple is putting on a insecure front, making their family and friends think they beat the odds are still so much in 'love' when really the realtionship has turned mediocre and/or boring.
