"Flame" is used as a verb ("Don't flame me for this"), a flame is a single flaming message. Also is likely to relate to the term lamer.

The peculiar thing about internet abbreviations is that many people make them up on the fly, therefore these abbreviations can often be confusing, and impossible to completly cover without being impossibly meticulate. This type of on-the-spot abbreviating leads to doldrums of such things as; OTP (on the phone), PO (pissed off), or the more common, OPTD (outside petting the dog). Another thing common to internet communication is the truncation and morphing of words to more typing-friendly forms. These may one day creep into common usage and end up in the dictionary. Some examples of this are:

• addy for address (addys is the plural)
• pix for picture (pix is both the singuar and plural form)
• prolly for probably

A special case of this last form is 'teh'. This is the corruption of 'the', and often pops up spontaneously when typing fast. So common is it, in fact, that it has made the jump to purposeful usage. Typically it is used in situations where one is being self-consciously enthusiastic, mimicking the less-grammatical Internet newbie: "That movie was teh suck!!", "The fight scene with all the Agent Smiths was TEH AWESOME", etc.

Internet writing is, by its nature, difficult to interpret, especially in chatrooms or on instant messaging, because much of it is quickly input, and many assume, falsely, their audience knows their body language. For instance; a LOL may be taken as genuine laughter or sarcasm, or as "whatever, stay away from me." So, for the sake of accurate and easily understandable communication, it is best to be as explicit as possible and make an effort to get your point across. Smilies such as :) can also be used to clarify emotional intent in internet messages.
