Rusty Train

When someone (typically a man) shits in someone’s mouth and then gets a blowjob.

“Saw you leaving with Sarah last night… how’d it go?”
“I shit in her mouth and then she blowed me. It’s called a rusty train.”

rusty taint 

The introductory smell of walking into a packed gym full of metal and sweaty people.

Hey Ron you ready to hit the leg press? Give me a second dude I’m trying to process this smell of rusty taint.
