A Hindenburg is not a specific sex move, but rather any sexual act which, when performed, is so deviant it prompts one's girlfriend to tell her friends about it, to which they reply "Oh! the humanity!"
In a pack pack of hot chick there is always a couple of fat cock blockers. they are always guarding the good stuff like trhe blimps did WWI. they also serve the same purpose as they did many years ago as they make approaching the hotties less apealing.
Me:"Well Judd I would go in and drop a couple lines to those chicks but thet're is a couple hindenburgs on our sixith, better pull out of this while we still can"
When you bang a big woman on your balcony. Midway before you bust a nut, you douse her with everclear, push her over the rail, and as she falls to her death you cry out "awe the humanity,"
