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.
