Quote by Cassandra Clare
That's why when major badasses greet each other in movies, they don't say anything, they just nod. The nod means, 'I am a badass, and I recognize that you, too, are a badass, ' but they don't say anything because they're Wolverine and Magneto and it would mess up their vibe to explain.
Summary
This quote suggests that in movies, when two tough and powerful characters acknowledge each other with a nod instead of words, it is a sign of mutual understanding and respect. By nodding, they convey the message, 'I am a badass, and I acknowledge your badassery too,' but they refrain from explaining it verbally as it would disrupt their cool and confident aura.
