It was made up by a genius, and is usually used in a situation where the speaker is not actually ded, but feels like they are, should be, or want to be ded.

adj. Ded is when you are dead from joy, hilarity, sexiness, or other great feelings as such.

There is a large difference between ded and dead. Do not confuse the two.

The verb form is 'deds' or 'dedded.'
