a willy
A willy is a fancy word for a penis and it's what you use when you don't want your mom to hear you talking about your junk. It’s like when you say ‘willy’ instead of ‘cock’ because you’re too lazy to say the real word.
I told my mom I had a willy and she didn’t even flinch.
My friend said his willy was broken and I thought it was a joke.
I used the word willy in front of my sister and she asked what it meant.
