Raj is a slang term used in the North of England to say someone is a bit mad, crazy or does stupid things, knowing that they are stupid but do them anyway.
Raj (slang) 'What are you doing ya Raj git? could have got someone killed!' or 'You see him over there?! he headbutted the doorman last week the Raj git'
A person that thinks they’re really cool but I’m reality they’re just an asshole. They use this emoji 😎 on a daily basis. They’re generally unnaturally tall. They have way too big of an ego and tend to bully everyone in sight. Pew pew.
