Nightcore?
"In 2002, Norwegian student Thomas S. Nilse (aka DJ TNT) and Steffen Ojala Søderholm (aka DJ SOS), both were born in 1986 in north of Norway,[1] started off the first track for a school project.[1][2][3][5][6] After being told by the teacher they will score 4+ for one song, they eventually made their first CD Energized which consisted of 13 tracks using the software Dance eJay 3 and they scored 6 for the project.[6]
Thomas S. Nilse and Steffen Ojala Søderholm used the duo name Nightcore, “Nightcore means that we are the core of the night, so you’ll dance all night long”.[5] After their first CD released in 2002, Nightcore using more advanced software, released four more albums.[5] The CDs were given to local DJs and whoever interested.[3]"
The name Nightcore is actually from the guys that started it as a school project. Other people who did pitched-up and sped up EDM music often use the "core" suffix.
Anything sped up though gets the label Nightcore though, so it's apparently very often misused.
Many people find it stupid because it doesn't take talent or much musical understanding to simply speed up and pitch a song and nothing else.
