Taken from the 2011 summer series "Friends With Benefits," a Mindbanger is the one significant other who gets into your head and takes over your mind in a way that all you care about is becoming like them and sustaining a clearly dysfunctional relationship. All you want to do is become whoever you think your boyfriend wants you to be, while losing yourself in the process.

A person who is mindbanged becomes completely disconnected with their family, friends, and previous lifestyle in pursuit of a pointless relationship.
"Oh...there goes Sarah, falling for her mindbanger, Joe"

"Yeah isn't he the guy who totally devastated her after she moved cross country for him instead of taking that big promotion?"

"That's what love can do..."

1. An event that occurs in which the subject could not have fathomed or foreseen its possibility.
2. Any "WTF?" moment
3. An event in which the mind is confused to the point where only the word "mindbang", can describe.
Your mom calls you and tells you that she has bought and cat and tells you to go home. You return home to find that ninjas have slaughtered your family. Your only reaction is..."MINDBANG!"
