In truth, I only have ever heard this, since joining aspie central and had to look it up and I think I am not too bad, if I pay attention. Although my husband would probably laugh in sarcasm at that.
What comes to mind, is carrying drinks from one end to another. I MUST concentrate on the drink in order to not spill it. As soon as my thoughts are diverted, spilliage occurs.
I often lose my sunglasses and they are my life saver.
My clothes will find all the hooks and door handles and have little holes in my clothes, as the testamony.
I am clumsy, but try very hard to take hold of myself and that is tiring, but rather that, then feel ashamed.
