A squished tube of cotton with a plastic thingy, used by women and boys who don't want to be caught with blood on their pants.

I tried to use a tampon like a pencil and it didn't work.

My little brother tried to use a tampon like a pen and it was a disaster.

Tampons are like the best secret weapon for girls.
