100% it sounds like this Frank retard only managed to get his nuts up enough to go through with this after convincing himself that Boogie was just being Internet Tough by saying he'd shoot Frank if he showed up at his door. Any nation other then the U.S.A. he would most likely be right. However in the States, even psychopathic manchildren have very little difficulty getting a firearms license (if they even need one, depends on the state) and a gun.
Once Frank knew his bluff had been called, he GTFO and retreated to talking tough on the Internet again. He surely would have preferred to go home with a GoPro filled with Boogie ignoring his shit-talking through the door and showing what a badass Chad he really is, but he got a hard lesson in reality. It's damn lucky he didn't end up in the hospital with a case of actute lead poisoning tbh.
And I don't even like Boogie in the slightest. I find him boring and predictable. And fat. But he's totally in the right to defend his domain from shit-talkers and stalkers knocking on his door.
Even though I live in a different nation, (and I know it sounds like Internet tough guy talk, I cant help that) if an avowed enemy came knocking on my door, calling me a fat retard and threatening my life, he would have found 20 inches of my Japanese pattern-folded steel ō-wakazashi (NOT a mall ninja Chinese replica) in his belly without so much as a word on my part.
