Used by girls on popular dating sites to make them seem more interesting than they really are. Spontaneous is synonymous with uncreative and unoriginal. Spontaneous people don't like to plan, because it requires too much thinking. They like getting lost while driving, because they're usually not the ones driving, they don't have things to do when they get home, and talking about scenery is a good distraction from talk about who they really are.
"If I could describe myself in one word, it would be spontaneous."
