What is it? memes (meams?) this is

I hear this word a lot now days and while I feel embarrassed to admit I’m about a hundred years behind the times, I’m not too embarrassed to ask anyway. What are they? and how is it spelled right? :o

TIA

A previous thread, including some discussion on “meme as image macro” vs. the more general concept coined by Richard Dawkins.

Here is the source for the word and concept. The meaning of the word has, ironically enough, evolved over time. (And ironically enough, the meaning of the word “ironic” has evolved over time, but that’s a different post.)
