Ermahgerd.

From knowyourmeme.com:

Ermahgerd (also known as “Gersberms” and “Berks”), a lisped pronunciation of “oh my god,” is an image macro series featuring a photo of a young woman holding several books from the children’s horror fiction series Goosebumps. The phonetically written captions are meant to sound like a speech impediment caused by the use of an orthodontic retainer, often using the snowclone template “Ermahgerd X.”

I have no idea why, but that little girl sends me into fits of hysterical laughter whenever I see her. I’m being mean and insensitive, maybe? Ermahgerd.
