Get the Medusa mug.
A free swimming infant form of sessile aquatic life. So called because of its whiplike protrusions which vaguely resemble the snakes that formed Medusa's hair.
"After self-fertilization, a single celled medusae is formed. This form is free to swim around, until it finds a suitable location, whereupon it will attach itself permanently and develop in to the sessile polyp form."

That one girl who if you look into her eyes even once, you'll start to fall for her. Lighter colored skin makes it worse, as it'll bring out the eyes more, making it more likely for you to fall.

When you incase your penis in cement, and then you stick your cemented penis into a female's vagina.
I just finished giving my girl The Medusa, she was knocked out cold after that, maybe i should check on her?

My penis suffered severe burns from giving my girl The Medusa last night.

Me and my girlfriend were talking about The Medusa. Later that night, while I was sleeping, my Girlfriend put my dick in cement, and she told me to give it to her rock hard, little did I know that I was about to rock her world with my cemented dick.
