How does my friends teeth stay white when he hardly brushes them?!
Question: My friend has really white teeth and you'd think his dental hygiene was superb. The truth is, he can go up to 4 days without brushing them. His breath smells but his teeth are still white.
On the odd occasion where I can't be bothered to do them one night if I've been drinking and just wanna sleep, they feel all furry the next morning and my breath smells rank and I immediately have to brush them.

I'm a dentist.
Some peoples' teeth are just whiter than others. The thickness of his enamel may be more than yours. His dentin may be less yellow than yours.
It could also be that he has darker skin than yours, which tends to make teeth look whiter.
Keep in mind, though, that white teeth get decayed just as easily as yellow ones! You can always whiten your teeth. He can never "un-decay" his teeth.
Unless he's been doing whitening treatments behind your back, I would put it down to lucky genes or diet- does your friend smoke or drink coffee? If he doesn't then his teeth are likely to be whiter than someone who does. (Although I would try and get him to clean them- they may be white but that doesn't mean his teeth are healthy and bad breath is definately gross!)
