Emergency Tampon - Phone Home! E.T Phone Home occurs when one is out on the town, skeezing it up in a bar, shopping for kicks and rags, or any other activity away from your mad stock of tampons at home. When one E.T Phone Home's they are calling home to ask a family member, pimp, or fellow drug dealer to hook you up with some tampons asap.
"Shit I need to E.T Phone Home!"
"Fuck I forgot it was that time of the month, can I use your phone to E.T Phone Home?"
