it's more of a cultural thing.
from what I've seen, from a number of African and European cultures, it's normal for men to hug, with guys kissing each other on the cheeks for some of the latter.
in the US, I've started to see more and more men hug with both arms, but it's usually the handshake/hug hybrid thing.
Don't you agree, Zach?
