Megalo

derived from Ancient Greek (μέγᾰς m. / μεγάλη f. / μέγᾰ n.)

Meanings are:

big, large

great, mighty, loud

marvelous, awesome

actually the same word that the prefix "mega-" means and is derived from.

That's a megalo event.

Megalo

A song that people make for their Undertale AUs.

1: "Hey, did you hear that new Megalo?"
2: "Nah, I don't fuck with that AU shit."

Literally everything that you'll see when you search for Undertale on Soundcloud.

Damn, I'm really getting sick of all these megalos on Soundcloud.

Megalo Strike Back

It's not a song not from Undertale but a halloween hack of Earthbound named "I Miss You".

Megalo Strike back isn't from undertale.
