The act of placing the head of ones penis inside the foreskin of another's penis.
David and Patrick enjoyed docking immensely because of Patty's stretchy foreskin.
Another reason Fruity liked docking with Barney D was because it was the only way Fruity could get his bellend covered with smegma. Circumsized guys cannot make smegma.
"Me and Miley Cyrus practise a lot of space docking cuz she has a large cheezy foreskin " ( as my aunt would say : "sometimes i dont have time to take a bath, so my dick smells like cheese" )
