Macrophallism is an indisposition or condition defined by an erect penile length measuring 2.5 SD+ more than average. Although the macropenis is defined by being something abnormal, the ubiquity of porn has made macrophallism seem normal. This has resulted in a lot of angst and shame for 90% of men who don't measure up. Macrophallism may be normal for tapirs, which are South American herbivorous mammals who have penises so long they sometimes accidentally hit themselves in the face with it. Nonetheless, tapirs are pretty mch shortcels. That's where horses come in. Horses are pretty tall and they are also pretty well hung. Is it a coincidence that horses are seen as sacred in the western world?
In the incelosphere, macrophallism is wdely consider to be a trait held by gigachads. Since most guys can't live up to this standard, we now have phenomenon such as double stuffing, whereby a woman has a threesome with two men inserting their dicks into one vag. Although the average erect circumference is 4.6 inches, combined, they become 9.2 inches of girth.
