He is a funny person, he likes to joke around and can sometimes be annoying but he couldn't care less. He is just who he is. He has the most amazing smile and has a handsome face that will attract girls (even lesbians) or (your) girl. He is nice and when you ask for something from him, he will most likely give it to you. He is smart and has a great sense of humor but most of the time he acts slow and will daze off while listening, looking at something or doing something. He is very trust worthy and can be trusted to do something for you or anything you need him to do. He doesn't like to judge but when he is provoked he will strike back and hit you with facts like crazy. He is thankful for everything he has. He prays for the best for himself and people he care for. People who finds him "annoying" just doesn't know what they are missing out on.

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.
