why?

While Brigette and Mac were in Portland a couple months ago for Laura and John's wedding a few more photos were added to the "Brigette-and-Lauren-act-like-idiots-and-hope-everyone-finds-it-endearing" portfolio.

Regarding the second photo, I believe the [online] conversation went as follows:

Brigette: This is why we're friends.
Mac: Trout lips is why you're friends?!?!
Lauren: Yes.

You don't have to understand it. But you should definitely laugh at it.
