People, especially in middle school, who try to be like the cool kids. These certain people often end up being ditched by their larger group of friends. In general, wannabes aren't liked or desired, and often considered annoying by a majority.

Wannabes appear in almost every social layer without reference to its cultural roots.
The word is a compound of "wanting" and "being" obviously, it can be interpreted as " to want to be", coll.: wanna be.

The wannabe himself is mainly a coincidental product of bigotry in combination with success the perverse wannabe met with in fact of a lucky streak or an immoral act.
Because of their narrow attitude to life wannabes can't realize their own incapability and, by mistake, reckon their whole past as the logical consequence of their absolute superiority towards other people.
In other words, those people are severely lacking of self-perception, receive backstrokes rarely and are neither able to revise the reasons for a failure (if occurred) nor for success.

A common indication of a wannabe is an abnormal and
and exaggerated self-confidence due to his/her utter self-overestimation.
Additionally, wannabes are behaving arrogantly and become exuberantly stubborn when they are alluded to their moronic self-perception, while criticism can cause them to overreact.

Wannabes are more often than not egoists, they like deceiving themselves and wannabes don't really care for others they can't profit from.

Finally, a wannabe's loss of reality makes him/her fail anytime and prevents him/her from having a fulfilled life, if he/she will ever become aware of the reality.

Anyone who makes an attempt to emulate another person/subculture/lifestyle; usually done to look cool, make friends, or to get attention. More often than not a wannabe is either insecure and wants to find their niche in society or they are just craving attention. These groups include "prep", "gangsta", "goth", "emo", "nerd", and "redneck" ("goth" and "emo" being the most popular). It all starts out when the wannabe sees a certain group as cool and then they try to adopt the style/attitude/musical taste of that group. This normally results in ridicule and the disgust of the people they try to be like.
