Guy 2: BTGG? What are you talking about?

A BTGG is the dream woman, the type of woman to drop everything to deliver a Starbucks drink in the late hours of the evening. she is the epitome of all things good in this world and the definition of beauty. A BTGG is what dreams are made of, and not nightmares but the dreams that feel so real that when you wake up it takes a few days to come to terms that your life will never be as good as that dream. A BTGG makes the pain of existence worthwhile. If there is anything every man should experience in his lifetime, it should be to have a BTGG in his life, who will care for and love him.
A BTGG is usually described as having larger-than-average chest lumps, dyed hair (usually pink or blue), and daddy issues.
