"Willy" is a term used in polite conversation instead of "penis". It is also a term used by kids.
The word, Willy, implies the penis in a flaccid state unless it is explicitly stated otherwise. By using the term "willy" it desexualises the male member and allows one to talk about cocks while your mother, wife, or grandmother is listening. Anyone older than this will need to be reminded what a willy is. Women use the term in front of males because they dont want to seem slutty by calling it a stonker, a beaver basher, or a tool.

Go and put some clothes on, Auntie Jane will be here soon and you dont want your cousin, Lucy, to see your willy do you ?

At the comedown party:
Oh wow until last night I had no idea how small my willy could get after dropping a mountain of pills - thats the first time i had to rummage around looking for it

girls gathering (boyfriend discussion)
I had to ditch him, he had a small willy and he never knew what to do with it. 1 out of two would have been sufficient.

Mom should I go to the doctor, my willy has turned green
thats funny I took a green pen that was leaking out of your trousers that were in the wash

willy is an extremely awsome person! He always looks on the bright side of things and has a tendency of making people laugh. I personally love willys and dont think i could live without them. Willy is also hott! They could get any girl they want and is very popular! They have very few enimies and a lot of people want to be just like willy!
wow he is really awsome, he must be a willy
