When a male grabs the lower portion of his scrotum with both hands, pulling it out and upward towards himself, leaving his cock sticking out like a "marsupial in the pouch". Ususally for the entertaiment of others.
The dinner party ended when john pulled down his pants and did the "marsupial".

A mammal with a pouch to carry its newborn in their infancy. But more importantly, NOT A PANDA.
A kangaroo is a marsupial, whereas a panda is not.

When a chick has a pouch, much like that of a kangaroo that sticks out and makes her less formal.
Wow that Danielle chick would be pretty hot, too bad she's a marsupial.

Marsupials are small mammals that are attached to the male body and as in the animal kingdom spend most of their life in a pouch. Only jumping out to surprise people!
When i crouched down to pick something up off the floor with my shorts on, my marsupials popped out!
