When you're about to have sex with a girl on her period... you turn out the lights so it's dark, flip her around into the doggystyle position, bend her over, pull her tampon out, and attempt to stick it in her ass in the dark as if you were blind folded and trying to pin the tail on the donkey. Upon completion, sex is mandatory but the return of the tampon to the vagina and/or Donkey Punch is optional.

When some little bitchboy is acting like a little tiny pee pee poo poo baby and messing up the group plans.
