Since many of the traditional frat boy style cockwaving activities (date raping as many girls as possible, eating semen off of cookies) are available on the
world wide web, a different indicator of penis length has cropped up among the dorks and failures of the messageboards. Usual indicators used are postcount, uptime, computer specifications, amount of RAM, hard drive size, "
first post" in a thread, and various other completely non-vital
statistics about one's computer. These "netcock waving" threads tend to start at least once a month on messageboards. A lucky person may find a thread full of pictures of the board's posters, so that their complete failure/dork status can be properly judged.
"Wow, he's got 20,000 posts, 4GB of RAM, and his
computer has been up for 3 years. He must have a
massive netcock."
