Circumcised

What does that word mean?

~its when your d*ck has a lot of extra skin on it~

No...
It's when the foreskin of the penis is removed.

well im not an expert, but it means when the skin protecting the (male part) is cut off, most likley when there born..

Mother Nature puts a sleeve of skin on the head of your penis. There's a small hole at the tip through which you pee. This sleeve of skin is called the foreskin. Circumcision is minor surgery to cut off the foreskin. If you were born in a USA hospital, you were probably circumcised right after your were born. If you were born elsewhere, you most likely are not. Circumcision is done simply because the mother asks for it.
