avatar - picture or image you choose to represent you in chat. Static pictures may be posted in some text chatrooms, 3D pictures are used in 3D chatrooms. Some chatters are av makers, that is, they make avatars for other chatters or for their friends. The wearer or maker of a great av is much admired. A great many av's used are simply unaltered pictures saved from a site somewhere on the net. Some large chat providers have a selection of av's for their members to choose from. However, these usually bear evidence of the heated imaginings of misogyny, as do most of those from clip-art sites. Usage examples: "hey, gillfish, love your av. did you make it?", "hang on. i’ve got an address for good av's". 'Avatar' is from Sanskrit. It's original meaning is the descent of a deity or released soul to earth in bodily form; incarnation; manifestation [Oxford dictionary, 1997].
