Here's what McGregor wrote in the caption, sans [sic]
Is that a tracksuit or a sauna suit Floyd haha wtf. is it hot in Tokyo or what’s the story here? that climate change is no joke fuck me hahah
It's hard to believe that Nasukawa is just 20, especially after his stoic response to McGregor:
Addressing him as "Mr." McGregor is way more esteem than the Irish fighter deserves. The fact that he wrote "please" also feels extraordinarily gracious—or, again, hilariously ironic—when aimed at a man who likes going to the gutter to hype up his fights. But just to show that he too can be petty, Nasukawa snuck in a subtle jab by bringing up McGregor's loss to Mayweather. Nasukawa may not beat Mayweather when they square off next month, but this kid is already a star in the making.
