Once and awhile, in frustration over differences in opinion on the meaning of a word, I seek comfort in the totally insane "Urban Dictionary". Here are some random (NO, not that useage) definitions from that site. It is so refreshing, and gives an understanding where our civilization is headed.

Random:
a word that follows no criteria or pattern. A word often misused by morons who don't know very many other words.
Correct: The decay of a radioactive isotope is random.
This is correct because nobody can predict exactly when the atom will decay. It actually doesn't follow a pattern.

Incorrect: Lol! Here r sum randome people I just met.
This is incorrect because the people have been chosen by a number of criteria: they are people that happen to be closeby and people who are willing to talk to you.

Incorrect: LoL here R sum randome words that I am thinking of.
The words are not random because you have specifically chosen them on the criteria that they are "suprirsing" or "unusual".


Random:
The most over used and misunderstood word in the english language. Commonly used by english teens, often buying into the fast growing subculture of emo. 1)Supposedly meaning spontaneous and off the wall by ignorant people. 2) how a large proportion of the myspace community describe themselves. 3) A way for morons to pretend they are capable of original though when actually every aspect of their lives is planned out meticulously with out fail.
Person A: and we said " mouse pad cups"

Person C: "quiet you mundane little twat, stop abusing that word. you have no concept of random that words to big for you. your misuse offends me. I ought to brick you"

Random   
The most annoying word ever. You'll say something that relates to your previous topic, yet they say it's random because they can't comprehen it.
