Dick in the door
When a male has a highly likely, but not guaranteed chance of getting hot action with a female. Chances of sex are gradually increased by "rounding the bases" or gradually increasing sexual tension between the chosen mate.
Brian's definitely getting that broad in the sack tonight. I saw them getting heavy in the parking lot, he's already got his dick in the door.
