Webvasion 

When a large sum of people from a group or multiple groups start flooding into a website or online community. Often normies, but sometimes other groups. This may be good or bad usually bad. May or may not permanently effect the website/community.

Facebook is immune to webvasion, as it's already full of normies.
4chan is also immune, as the current community is so disgusting most people leave immediately.
Youtube's already been webvaded.

webvulsion 

webvulsion is a visceral and immediate, gut level, negative reaction to something or someone one sees on the web.

I almost threw up when I saw that youtube skateboarder's nutsack split open on the grinding rail, it was a total webvulsion dude!

I am having a severe webvulsion to that dude on eharmony.com!

The entire World Wide Web nation.

I joined the webnation today when I visited my first website. Google is the webnational search engine of choice. Webnationally, porn sites are probably the most visited sites.
