So, is what you're smelling, more like rotten eggs OR raw gasoline ... ??

If the smell is coming from the exhaust, my experience is that this happens to my car every now and then ...... usually after a cold start, when I'm backing out of the driveway. Nothing to worry about.
If the smell is coming from raw gasoline, I'd suggest you have it looked after ASAP (as suggested above).

Hum nailed it! I bounced the cat on my Talon off a speed bump once and had a smell so close to the mercapton in my car for a couple of days that I thought I was a natural gas plant.
I also get it briefly in the FRS usually like Hum said when backing up but also sometimes on the highway when I pass a truck and the vortex around the car gets messed up.
As long as it isn't an actual leak in the exhaust it isn't a problem. If it is a leak get it checked and don't nap with your car running.
