It is kinda the same thing when someone goes sicko mode, but this is just times a 100.
A rumor actually says that Waluigi is the father of almost all people on earth, and thats why nearly everyone can go WALUIGI MODE.

A time, initiated by Waluigi or another party who favors Waluigi. When Waluigi Time is in effect, all other actions at that moment are to be stopped, and all attention must be focused on the shenanigans and mayhem that the starter is allowed to cause. Can also be used to render another's argument invalid. One is also obligated to yell "waaaa" at random intervals. Crotch chopping is optional, but approved.

Inspired by the hilarious webcomic Brawl In The Family, when Waluigi made his eponymous appearance, and was so well liked he made repeat appearances.
John: Hey, what's up?

Harry: Nothing. Hey did you see--

*Waluigi drops in*

Waluigi: WALUIGI TIME. NOW THIS SITE IS FUNNY AGAIN.

It is a form of sexting where the prefered moaning sound is Waluigi's "WAH" instead of something like "YEAH" .

Can be implemented in real life if that's your kink .

Someone who doesn't like the all mighty Waluigi. They usually don't have too many reasons why they hate him. But they sometimes have 1 or 2 good reasons why, which is usually countered by someone who does like Waluigi
