When a man has either been riding in a car some or let's face it, he's gone all day working outside and it's beyond musky down there; it's gross!
Oh baby you got that hcd (hot car dick)! I ain't going down there until you shower that dick off.
When you have been riding in the hot car and things get a bit musky down there.
Baby, I gotta take a shower before we have fun because I got hot car pussy.
