Milk delivery 

A term repeated in the automotive parts sales industry to signify fear and uncertainty. Outside sales teams fear the 'milk delivery' and will avoid it at all costs.

The manager, unshaken, locks eyes with Tony, the outside salesman and simply says 'milk delivery'. Tony knows what this means but fears he has the courage to face it.

Reverse Milk Delivery 

When a girl is giving head to a guy and when he finishes in her mouth the girl pretends to swallow. The girl then leans in for a kiss and when they kiss she dumps his load in his mouth.

A girl was giving me head and when I finished and she wanted a kiss I knew I was going to get a reverse milk delivery.
