I asked three people I know this question:
"Is it bad that this song called "okaasan" reminds me of sketch hitting Frank in the beginning of his videos"
The first person I asked was Sroeland000

she listened to the song, I asked what was her first thought, she gave me an answer that I don't understand.
The second person I ask was REDDIE4LIVE

I'm new to Snapchat
I did ask her tho
It's just that the chat didn't show up anymore
But she responded with "ptffff"
Third person I ask was ElijahBestIsMine

Then down we went to snappychat

I can like whatever I can. It's 2018

There are other vocaloid songs that are nicer, like levan polkka and fukkireta

I wanted to say "if you don't get..."
Japan is my city

Then she went donate money to charity

Out of all three.... it was a "what?"
Probably because they never listened to the song.

Meaning:
Sroeland000 kinda already knows the meaning because I told her

According to akidearest... the song is about a mother trying to kill her own daughter. And miku (the singer) tells us, the viewer, to run away before her mother comes.
And it reminds me of sketch hitting Frank at the beginning of his videos....
My favorite part in the song is when miku starts to break apart the word "mother" in a creepy glitchy way.
And when that part plays I imagine sketch ripping up Frank. Don't judge me. I'm weird, I kno.

Lyrics:
Kuru x3
Twisting
Mawaru
The neck
Kubiga
Is twisting
Gishi x3
Sqeak
Otowo tatete
Making that sound
Okaasan gairu
My mother is here
Kubidake mawaru no
Only her neck will be twisting
Okaasan womiru
My mother will look at me
Watashi no kubiga
Where my neck is
AAAAAAAAAAAaaaaaaaaaaa
O-o-o-ka-ka-ka-aaa-sa-sa-a-aaa-an..
M-m-m-mo-mo-mo-th-th-er-er-er-er
Okaasan gakuru
My mother is here
Kubidake mawaru no
Only her neck will be twisting
Okaasan gakuru
My mother is here
Kubidake mawaru no
Only her neck will be twisting
Okaasan gakuru
My mother is coming
Hayaku nigenaito
You must run away now
Okaasan gakuru
My mother is coming
Mouoistukareta...
She already... got me...

But the song in reverse is probably more creepy than the original

I'm sorry 4 all the nightmares you'll be having tonight
