Once De Mayo

The Eleventh of May. A day of celebration for teenagers of English, Dutch, or Swedish, decent across the U.S. but primarily in Southern California.

Nathanael: "Don't forget about May 11th."
Wesley: "I couldn't possibly, you've only told me like a hundred times."
Nathanael: "Haha."
Wesley: "Don't worry about it, dude. It is Once De Mayo after all. We're totally gonna party."

I'm hit once then deada

Well, that's what it sounds like, but it might not be what he said. Although "then deada" rhymes with vendetta, the meaning isn't entirely clear. "Hit" can mean shot, so it could mean that the girl is so attractive that seeing her is as powerful as being shot - like being "knocked out" by her beauty.

once

A hypocritical fandom that thinks they are sweet, nice, and passive aggressive but then goes around bashing other groups. They think they are one of the most chill fandoms out there but are the main causes for fandom wars. Each and every perosn of that fandom on needs a fact check because they are just plain rude

Twice is the best GG out there, we onces are the nicest fandom because we never bash anyone.
