In a really strict reading every idea is a meme.

Though thecontext matters imho. Personally a meme should be something created, or shared, that picks up a new type of meaning along the way. If a stirn of text is pasted there isn't any meaning added. It's just lazy.

I like my memes just a sliver above lazy, I like them low effort. Same difference between a raw steak and medium rare. It's not much, but it makes alle the difference..
