In my first place there was a guy, we'll call him S.
So S. was not very popular, he had an intimidating look all the time, wore workout dryfit clothes and seldomly smelt like he didn't take a shower in quite a long time. He has an iOS developer on my team. He was blazingly smart and called every code he saw garbage. Nice guy indeed :)

He was a fine guy after you got to know him and get accustomed to his weirdness... Smelly nonetheless :)
