The Brief: An expression meaning "Oh my God" or "Oh my goodness," to indicate a surprise or shocked emotion.


OMG stands for “Oh my God” or “Oh my goodness.” It’s commonly used in texts or tweets to denote a shocked or excited emotion. It can either be written in all caps, or lowercase as “omg,” to convey a less dramatic tone. A variation of the expression is ZOMG. OMG has been used in memes like “me on Ellen,” where a guest on Ellen DeGeneres’ show is overwhelmed by the host’s absurdly grand surprise gift.
