Manmark
A man who is so tall that he can be used as a landmark in crowded areas by his friends or the people he is traveling with at the time. Tall enough to noticeably stand out among crowds, the Manmark can be used by his fellow travelers to prevent becoming lost in a sea of people.
The Beijing Silk Market is so full of people and different things to buy that our group would naturally become separated - it's a good thing that Wes is a Manmark. As long as we can see him, we know we're at least close to everyone else!
