Don’t you just get bugged by stupid comments? Why do people leave messages for Piolo Pascual on this site thinking he will read it? For those instances, I’ve installed a Douche Bag comment plugin. If you see this image next to a comment, you know what it means.

A douche is a device used to introduce a stream of water into the body for medical or hygienic reasons, or the stream of water itself. The word comes from the French language, in which its principal meaning is a shower (it is thus a notorious false friend encountered by non-native speakers of English; the phrase for vaginal douching is douche vaginale, meaning vaginal shower).

From Wikipedia
The word can refer to the rinsing of any body cavity but usually applies to vaginal irrigation, rinsing of the vagina. A douche bag is a piece of equipment for douching: a bag for holding the water or fluid used in douching (the term douche bag can also be used as an insult; see below for slang uses). To avoid transferring intestinal bacteria into the vagina, the same bag must not be used for a vaginal douche and an enema.
