Trip Metal 

Trip Metal is a term that was conceived by John Olson of the band Wolf Eyes to categorize the band’s sound which originated in a meme that helped popularize the term. The genre covers a wide variety of what once constituted the noise music scene. An annual Trip Metal Fest, curated by the members of Wolf Eyes, showcases many of the acts that fall under the genre which takes place in Detroit and in recent years has spread to other cities in the Midwest.

John Olsen (sic) christened the phrase when he tweeted a photo of a wolf—fangs bared—with a declaration that his band embodied "Trip Metal."—ostensibly to highlight both the psychedelia and the aggression of his band's sound. -via Thump

Spite Monkey Mentality

The sort of mental attitude exhibited by the majority of teenagers worldwide; arrogance, inexperience, and self-absorption coupled with lack of insight, narrow mindedness and a total inability to accept that they could ever be wrong. It is just this sort of chip on the shoulder attitude that causes them to clog up Urban Dictionary with ridiculously silly definitions that stand no hope of ever being accepted, to compete with each other to produce the most sickeningly disgusting sexual perversion, to attempt to boost their, already over-inflated, egos with self-aggrandising descriptions of themselves or to denigrate people they don’t like with descriptions that they don’t have the balls to put their names to, because if they did they would be sued for libel. It’s the sort of mental attitude that, when their submission is rejected, throws all of its toys out of the pram and rejects everyone else’s definitions out of infantile spite.

It is to be hoped that eventually they will grow up and maybe grow a pair although it must be said that many of them never do, retaining even into old age an immature sense of entitlement.

Spite Monkey Mentality is unfortunately prevalent amongst the teens, pre-teens and post teens who have invaded Urban Dictionary.

Mental Wealth 

To have mental wealth is to possess the knowledge, skills and resilience to maintain and enjoy great mental health, even in tough times. Mental wealth helps us to thrive and protects us from having poor mental health.
Mental wealth is something everyone has a right to.

It means understanding what makes us human; how to regulate our thoughts, feelings and behaviours so that we play our best game and help others to do so too.
