In Hunter x Hunter, there is a shotacon magician/clown who is arguably one of the strongest characters in the series and fairly important to the overall plot. His ability is called Bungee Gum, and it is the power to make his Nen (spirit energy) have the properties of both rubber and gum, that is, sticky and stretchy. He says this fairly often. Now, it's worth understanding that the whole "rubber and gum" thing was a long running joke in HxH threads for years, because it's funny and, again, the Clown says it like a catch phrase. The joke was ALWAYS that you can't beat rubber and gum, it can do anything, because it's rubber and gum, can't beat that, nope.
Now, in one of the most recent chapters (and by recent I mean, it happened three years ago but there's only been 30 chapters since then) where the clown was in a death match with someone he's been trying to kill since the 90's, he fucking loses! He gets stomped and styled on so bad he dies. But guess what? Rubber and fucking gum, he uses this ability to knead his heart and lungs post mortem and bring himself back to life. And he does so by evoking a contract with his Nen (which is an established mechanic of Nen in the series), and his evocation was translated by mangastream as so: "O' my rubber Nen"
This single handedly took a long running joke to an extreme no one thought possible, I mean talk about meme magic, and completely subverted all expectations for how Hisoka's character arc would develop, as well as other more extreme consequences to the plot like killing off 2 members of the main group of antagonists. The meme has been a little forced in recent times but it's worth understanding just how far back this shit goes, and just pivotal this single phrase will be in the plot of HxH.
