Tagging Photos Accurately

Is it OK to tag your friends in pictures that they aren't present in? For example, if there's some pic of a drunk guy throwing up in a bar, can you tag your friend as that guy if its not him? What's the etiquette on tagging photos properly. Edit this page and add your thoughts.
*It is only acceptable to tag your friends in photos not of themselves if the photo is obviously not them, meaning nonhuman photos. You may tag animals, cartoons, or objects (such as a beer can or written letters). Do not use other people as this can be quite misleading.
*Do not tag photos of someone's hand or foot because it confuses people as to who is in the shot.
*Do not tag photos of someone who is partially visible and not the main subject of a photo.
