A particular type of girl who will drive upwards of 15 min to your house to have sex with you
once a week from 8-9:30pm. She is allowed to visit other times only if she is bringing food.
She cannot enter the house though. She is not your girlfriend.
Guy 1: Is that your girlfriend
upstairs?
Guy 2: No, she's my
8-9:30 girl.
Guy 1: Do you have plans tonight?
Guy 2: No, my 8-9:30 girl is just going to drop off some
lobster.
