An annoying, autotuned thirteen-year-old which hit teh interwebs in mid-February 2011. Her "hit" single, "Friday", spread over websites such as 4chan and Tumblr mid March 2011, making it a new meme.
"Friday" features such hit lyrics as:
"7am, waking up in the morning
Gotta be fresh, gotta go downstairs
Gotta have my bowl, gotta have cereal
Seein’ everything, the time is goin’
Tickin’ on and on, everybody’s rushin’
Gotta get down to the bus stop
Gotta catch my bus, I see my friends".
This "internet sensation" was also featured on Tosh.0 Wednesday, March 16, 2011.
1- Have you heard that new Rebecca Black song?

The singer (if she can even be called that) of "Friday", the most infamous song sweeping the nation as of 3/18/2011 that will probably forgotten in two weeks.

It's remarkable that she's famous because she's unattractive, a horrendous singer, and 13 years old.

To drive the point home, she is worse than Justin Bieber. But she did teach me the days of the week.
Rebecca Black's song Friday

"Yesterday was Thursday, Thursday
Today i-is Friday, Friday

We-we-we so excited
We so excited
We gonna have a ball today

Tomorrow is Saturday
And Sunday comes afterwards"
I don't want this weekend to end

The lyrical genius who created the classic hit song "Friday". Her song swept the nation, her catchy lyrics, such as "Yesterday was Thursay, today is Friday, tomorrow is Saturday, and Sunday comes afterwards", clearly redefined our views on the days of the week. Her constant questioning about which seat she should take demonstrates the troubles of an average teenage life. She is one of the greatest artists since Mozart.
"What day is it?"
"Just ask Rebecca Black!"

The reason we can no longer look forward to Fridays or the weekend. The worst singer ever to make an official music video and have millions of hits on youtube.
Did you see that new song "Friday" by Rebecca Black?

I watched 10 seconds and wanted to rip my eyes out and destroy my ear drums.

A 13 year old girl whose song "Friday" is the worst song of all time, bar none. Some are now calling her the "new Justin Bieber".

Her singing sucks donkey dick but her video on YouTube has gotten millions of views. This unfortunate phenomenon just shows how low the music industry has fallen.
Guy 1: Hey, have you listened to Rebecca Black's song? It's pretty fucking bad...

Guy 2: Fuck man, that's an understatement. I swear, as soon as I heard that shit my ears started to bleed, I started foaming at the mouth and my dick fell off. FML

A girl who can't make up her mind on which seat she should take, in the car driven by her 13 year friend. She likes to narrate her Fridays in extreme detail from 7:00 am to friday night. She knows her weekdays very well to the point where she will tell you that yesterday was Thursday, today is Friday, tommorow is Saturday, and after that is Sunday. This song is only accurate on Fridays, so do NOT rely on her when you need to know what day it is. Rebecca Black says she enjoys her Fridays, despite the fact that there is a random black guy stalking them in his car. Maybe if everyone in the car wasn't so busy dancing and driving underage, they would notice and call the police.
Example: Now i'm aware that Saturday is after Friday, thanks to Rebecca Black and her wisdom of the days of the week.
