Similar to dine and dash, fucking and dashing is the act of having sex with a prostitute and skipping out on the bill. The legality of this act is in question because one is not technically paying for sex, but at the same time they are committing theft of services.
James: Yeah, after we finished up, I realized I didn't have my wallet on me, so I pulled a fuck and dash.

Jordan: This is why you gotta charge in advance if you're hookin', man.

Get the fuck and dash mug.
Going back to a particularly good past sexual partner at the first opportunity.
"He just clicks his fingers and you run, its a total fuck-dash"

"Y'know I think he's still interested in me..."
"O this is gonna turn into such a fuck-dash"
