When a girl is on her period, you begin to eat her out with a tampon in her. While eating her out, suck on the string hanging on the tampon. Thus creating a rat tail out of her vagina and in your mouth.
John: Dude, natalie was on her period but i didn't care so i pulled a rat tail on her.

Brandon: Fucking sick brah.

When a girl sags her pants so low you can see the top of her thong, aka underwear that has a string in the back for your asscrack.
