Tampon

Something that girls jam up their vagina when they get their period. IT can be VERY uncomfortable if inserted incorrectly. If left in long after the max time (8 hours), a life-threatening, possibly fatal infection may sometimes develop. There is a common virginity misconception about this. Only a PENIS (possibly a dildo) can make you lose your virginity.

Shannon! I'm on the rag, I need a tampon!
You'll get TSS, you silly girl!
Oh! Give me a pad. Good we have EDUCATION.
