I have been best friends with him for nine years, and I am happy to have built such a great friendship with him. However there's this one problem that's been bothering me for a long time, his hygiene. He smells like shit, never takes care of his own body, and wears the goofiest (for a lack of a better word) and dirtiest of clothes. He's a dirty bastard and he knows it, but for some odd reason, he doesn't care if he looks like a slob.

What's even worse is that he makes excuses about it (such as excessive sweating), says that some of the practices aren't "manly" (such as facial exfoliation), and complains about being single. He may be my best friend and someone with an admirable personality, but that doesn't mean I will not say anything if it bothers me. If there's a problem, I will address it.
<bot>: My best friend smells like shit and he doesn't care. What can I do to make him realize that it's bad to have poor hygiene?
