FatTok 

A euphemism for the fat “activism” on TikTok. Most commonly associated with extremist ideas of “fat acceptance” and body “positivity”, as well as “healthy at every size”.

“Damn, so now some fat influencers on FatTok are claiming that wanting to work out is fatphobic.”

Simon: You're such a fucking fattock.
