Mukbang is one of those things I sincerely can't see the attraction of.
Epic Mealtime, sure I can see that. (I know it's old as fuck, but best contrast I can come up with) They make huge amounts of exceptional garbage food concoctions, many of which you'd honestly love to have a taste of but are never going to make. Then as many of them as possible sit down, loaded to the gills and hungry as fuck, and tear into it. With 6-10 people chowing down, it's not a total waste, nor are any one person getting more then, say, 3-4000 calories. Gluttonous, but not going to kill you once every few weeks.
These mukbang fucks are almost always deathfats, or they become that way soon enough (Niko) they put together DISGUSTING ingredients that don't even sound good together (this mountain of cheese and noodles drenched in trendy hot pepper sauce is a perfect example) and gorge on them on a sometimes daily basis! The smarter ones puke most or all of it up after filming (which is a disgusting waste of food and pisses me off) but WHY would you be attracted to watching that?? I can sort of see the lolcow appeal, but once you've seen one of these walking corpses gag down 10,000 calories grinning like a mortician's advertisement shot you've seen em all.
I know Niko's schtick is to be a trainwreck and bawl on camera while he stuffs himself to death, and that's smart even though he's a piece of human shit. The rest of them, WHY??
