As well as binge-eating various fast foods, the trend also sees the stars chow chomp away at huge feasts of ramen noodles, pasta, cereal and spicy buffalo wings.
And while the trend originated in Korea, it’s now built up a huge following in Britain, the US and even Australia - with fans describing the videos as a ‘turn on’ and a ‘stress relief’. OK, then.
One fan told US Today: ‘I prefer the seafood, crab and ramen videos..
‘While watching others eat rich food you can fantasise that you are eating it. For me, I associate food with pleasure. So, watching these videos makes me feel happy.’
But not all mukbang fans have had good experiences watching the videos - but admit they can’t give them up.
‘I started having erection problems,’ YouTube mogul Nicholas Perry tells The Sun. ‘It never happened until I started doing mukbangs.
‘I can’t fall asleep because I feel like my digestive tract is on fire, and then I’m running to the bathroom. I’m sitting on the toilet crying.’
Regardless the trend is certainly gaining momentum with US mukbang star Christi Caston saying she’s earning double what she did working nine to five.
‘I mukbang every day, and I make a comfortable living from it,’ she told Today.
