Ermahgerd (Maggie Goldenberger)
"Ermahgerd" is a rhotacized pronunciation of "oh my god". The meme first emerged on March 14th, 2012, as a post titled "Just a book owners smile…". The girl in the meme, Maggie Goldenberger, said that the picture was created in fourth or fifth grade when she and her friends seriously got into playing dress-up.
