"Wannabeme" is a kind of show off attitude of someone who gained financial or any other kind of social success, especially while still in his/her young age.

When you got lots of money, fancy car, big luxury house, an yacht or even a private jet and showing it aggressively to the public, you are shouting "I know you envy me, you wanna-be-me and have all this, what I've got".
1. I'm fed up with this totally ignorant "wannabeme" dude, and all his show off parade...

2. His puffed up walking is screaming "wannabeme"!? What a fool!
