I think this song is actually a metaphor for life, and the journey we all go through.

'in the car i just cant wait,
to pick you up on our very first date'

meaning a date with fate or destiny. he has transposed his actual feelings of fear of the unknown into a light hearted pop song about girls, but he's actually talking about the battle raging inside himself between good and evil.

'when you smile i melt inside', the good side of him
'im jealous of everybody in the room' - the envious bad side, also the line
'please dont look at me with those eyes', the devil seeing straight through him
