What is one trait that you immediatly find unattractive?

This could be in friendships, work, dating and etc. This could be aesthetic or in personality and so forth. What trait in someone is an immediate no for you? For me its people who are racist, objectify people, or make fun of people for things they cannot control (like conditions, burn scars etc)
