1. Peeny smoosh is what happens to your penny when you put it in the machine at the zoo that smashes your penny flat and into an oval with a giraffe, gorilla, or some other commemorative animal.
2. Peeny smoosh is also what happens when you smash so much that your penis nearly gets turned to mush.
Miranda and I smashed so much that I think my peeny smooshed. Ouch.
