If a
person is found unconscious, with a ligature around their
neck, phone in hand, browsing a site with abundant
teen pornography such as TikTok, they can be said to be taking part in an online challenge.
Can be used more generally to describe viewing TikTok pornography even without autoerotic asphyxiation.
"What are you up to tonight?"
"Well my mum is working again so I'
m going to give taking part in an online
challenge a
try"
