I lol at the people who say Naruto,the dude is just plain reckless,he doesn't think of the consequences of what he does
Sasuke showed dem manly ballz when he decided to go up against 5 freaking kages,with a cold mind and ballz of steel and a straight face
But the most manly man in the Narutoverse is Sandaime Raikage,the dude stalled an entire army single handedly,freaking 10000 shinobis vs one...Hands down that's the most manly display of dem titanium ballz a man can display
Top of that he went head to head vs the eight tails,and by head to head i mean a manly match of strenght, not sealing s**t,just mutual pwnage
