When a person who is part of a culture or community identifies so strongly with it that they rarely talk about anything other than how much they love said culture and thus develop tunnel vision and narrow minded behavior.
Example 1: Tyronda's tumblr has over 300 posts about how proud she is to be black and how eminem's music is cultural appropriation. I think she has a cultural masturbation problem.

Example 2: John is always going on and on about the achievements of white people and how many things they've invented even though he hasn't accomplished anything himself. I think he suffers from chronic cultural masturbation.
