Not strongmen or sumo wrestlers, obviously. It's the deathfat-tier males(and sometimes she-whales like Raging Chestpain) who are very visibly obese with little to no muscle tone but boast about how much stronger they are than a gym regular who's smaller than them but way more lean. They then proceed to claim that their obese appearance is caused by the muscles taking that particular shape when it's very clear that the human muscular structure does not look like that and it's just their bodies being encased in unshapely lard.
