A gas station bathroom.
...or were you implying something else?
Tarmacking. Look it up on urban dictionary
A girl I know from school told me about this time her boyfriend was so horny that he would do anything to have her at that moment. She said but I'm on my period. He says, I don't care. And left the room. He came back with a straw. He pulled her pants down, tugged out her blood soaked tampon, stuck the straw up in her vagina and slurped out the blood until he had his fill. She said she was so turned on that she proceeded to make out with him, two girls one cup style.
Dirt.
