reeenius 

Reeenius is the fusion of the words 'retarded' and 'genius'. To make it more retarded, it's written with a triple 'e'. The characteristics of a reeenius person are being fun, dumb and weird but either way still somehow being intelligent. A reeenius person knows a lot of memes, dumb jokes and insiders (preferably, has dark humor and is sarcastic or ironic).
If you encounter a reeenius person, be aware of getting a lot of dumb jokes thrown at you and (of course) weirdness. If you have someone reeenius as a friend, appreciate it. (You can expect a lot of fun time in the future with them.)
There's also a special term for the group of reeenius people, 'TeamReeenius'. It also has it's own hashtag, '#TeamReeenius'.
Manita: 'Why are we doing this again?'
Banita: 'Cause we're freaking reeenius.'

Jochen: 'Wow, you guys are weird.'
Banita: 'No, we're just reeenius.'

Paul: 'How would you describe her in one word?'
Manita: 'Reeenius.'

British slang for a scientist or technical expert, esp . when the speaker is not certain of the expert’s specific field of study. Not necessarily derogatory, but typically used by persons without a technical background. In the US, the equivalent would be “egghead”, “squint”, or “geek.”

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.
According to the boffins downstairs, the murderer used a serrated blade.
