Creamy Dill Inheritance Pickle

When every boy in your boyfriend's family has a large penis, 'inherited' from their ancestors.

Boyfriend: Babe there's something I need to tell you
Girlfriend: What is it Johnny? Are you breaking up with me?
Boyfriend: No, it's not that I just need to tell you something about my family.. We are known for our Creamy Dill Inheritance Pickle.

Girlfriend: Wow! I never knew how lucky I was!
