Hi everybody! How's my peeps?!

I'm trying to create a document that has no embedded fonts. I thought, all I have to do is turn all the fonts I use into outlines (Illustrator) however, one font keeps creeping into my document as an "embedded font subset" (whatever that means). I am not even using this font that keeps showing up as an embedded font. Why is this happening? And what can I do to get rid of this pesky font that's not even in my document at all?
