Pack of Dimes
A guy’s pecker is so small, it looks like a pack of dimes. It’s not even close to being impressive.
I saw his willy, and it was like a pack of dimes. I almost cried.
He had a hard-on, but it was still just a pack of dimes. Sad.
That guy’s dong is like a pack of dimes. He’s got the worst boner in the whole school.
