muddin and to the car wash

To go muddin and to the car wash is when you rail the fuck outta someone's asshole (muddin) and then make them suck your shitty cock clean (car wash) often used as an alternate route if one is on the lube rack.

I asked Suzie if she wanted to get a six pack and fuck but she didn't like to drink. So I went muddin and to the car wash instead.
