A Wally
A weird word Bill Cosby used for a guy's pecker. It's like calling it a 'big, flappy thing.'
My brother said his dad's wally-wally was bigger than a pizza.
My mom said Bill Cosby's wally-wally was so big, it made the toilet clog.
My cousin said her dad's wally-wally was so big, it made the whole house shake.
