Get the boner snorkelmug. When your in subway, ask for a Boner Sub. A boner sub is a hard dick inside toasty buns. That's why it's my favorite thing to get topped with Mayo.
I can't wait to get my favorite boner sub from subway so I can take it home for delicious and messy results. Boner subs are the best!
