Breaking the Firewall is when you're ejaculating, but you keep fapping for another round. Some people claim that people who can do this technique are "legends".
Girlfriend: "Why are you making such weird movements while fapping?"
Boyfriend: "Sorry, babe. I'm currently Breaking The Firewall!"
Boyfriend: "Sorry, babe. I'm currently Breaking The Firewall!"
