The cleavage seen when a women is wearing a very high cut top. Basically, the tops of the breasts will be covered but from about an inch below the nipples and down will be bare. The word is a portmanteau of "cleavage" and "nether" (meaning under, or below).
Did you see the nethage on that girl back there? She was practically topless!
Netrage (Or just "raging") is the opposite of Netiquette. It's when a social networking site or comments section has been taken over by angry, ignorant people who shout obscenities (in all CAPS) and misspell everything they type. These "Netragers" travel in packs across the internet and ALWAYS miss the point of whatever they're commenting on... They are completely hostile and love to gang up on polite, mature people. They are also sometimes called Rage-aholics because expressing constant outrage and anger is an addiction for them.
I had to shut down my computer and go outside for a walk... All the NetRage was getting me down.
I know your IQ is lower than the temperature in November but could you stop Net-raging on me? I was only trying to answer your question.
