Ermahgerd Chrerstmahs is a phrase that in normal talk would be Oh My God, Christmas, which is the translation.
This meme character, the Ermahgerd girl, came to be an internet meme sensation in 2012, and although two women have come forward claiming to be she that inspired this meme, as well as thousands of others, there has been nothing yet conclusively proven. In other words, nobody really knows who she is. This picture is obviously not the original and features a different girl. Hey, kid, come forward and tell your story right here! We won’t laugh at you. A lot.
