Thunder Gun Express is the most badass action/romance movie from "It's Always Sunny in Philadelphia"....and it has dong.

Thunder Gunned means "without hesitation" and badass. Doing anything that would be considered bold and brave would be Thunder Gunning and make you cool.
Thunder Gun, the main character, is supposed to have a nice dong in the movie.
"No hesitation, No surrender....Thunder Gun Express!"

When Frank stole a riverboat with Asian tourist, that was pretty Thunder Gun!

Charlie Thunder Gunned through the sewers to make it to the theatre by himself.
