passing crush
Refers to a feeling of amorous admiration that you experience when catching sight of a hottie in a vehicle that goes by you on the interstate.
I had a passing crush on an auburn-haired hottie driving a convertible whom I saw while riding Greyhound. Fortunately, there were several other attractive likeable gals for me to hang out with at the next bus station, and we all had a two-hour layover in which to share friendly banter, so I pretty much got over the redhead; one of the placid-faced cuties at the station even comfortingly reminded me that the sports-car chick's "rare 'n' glamorous" tint had most likely just "come out of a box", anyway, especially since she looked somewhat Asian and didn't have any freckles.
