Deeding

To provide a selfless good act out of the kindness of your heart.

Will - Hey let's go deeding!
Everyone in the world - We should, I just got deeded last week!

Fill two needs with one deed

To achieve two simultaneous goals with a single action.

A less violent alternative to the phrase 'to kill two birds with one stone'.

I needed to post a letter and buy some bread, so I though I'd fill two needs with one deed and stop at the mailbox on the way to the store.
