This is most commonly used to describe Korean celebrities with a strong personality. It may also be used to indicate that a person has a very strong individuality or a unique personality.
This is derived from ordinary people being "3d", so a person which is so quirky and thinks outside the box is considered "4d" or 4-dimensional.
I knew my friend was 4D! She always introduces out-of-this-world topics.
Daebak! His 4dness is starting to rub on me!
you seem to be able to read body language better, and figure things out, but way too lazy to move, and in my case my limb's such as my legs and arms, seem to move to the sound of music without my control.
everything is warm in 4D and you generally feel good, but you can ffeel down when you realise the faults of your friends, and what makes you feel down is that your thinking about your friends in this kinda way
but end of it's all good.
the term for this 4D orginated in wolverhampton, by a guy called amit
Amit"no everythings 4D"
Emma:"Amit you getting 4D today?"
Amit: "hopefully :D"
There are conjectures that there may be ten total dimensions, even more, or even an infinite amount. The thought concerning dimensions past 3D is generally in the realm of the theoretical.
