Megaloomers

A group of obese children who have never been touched by a woman and spend all day on FL STUDIO 10, 12, or 20, sweating their balls off attempting to perfect each instrument used in MEGALOVANIA. These people tend to use racial slurs, and also DOX people. They hate the LGBTQ+ Community despite being the most closeted people you could ever meet.

"Hey guys, I just found out MEGALOVANIA has a hidden melody In the brass section, I think it's the Mother 3 harp bitcrushed!"

"What the fuck?"

"Oh don't worry, he's just one of many Megaloomers"

Megaloomer 

It's someone who recreates and/or "rips" the song Megalovania from Undertale. They'll also try to make a sans joke at any second they possibly can.

Person 1: Did you hear that Jacob made a song and it incorporated Megalovania in it?
Person 2: Isn't this the third time?
Person 1: Yes
Person 2: What a Megaloomer
