Origin Story

“OMG” predates the internet — the abbreviation first appeared in a 1917 letter to Winston Churchill. But as a hashtag, #OMG became one of the most-used tags on early Twitter, expressing shock at news, celebrity moments, and everyday surprises. Its universality and brevity made it perfect for Twitter’s character limit. The Usher song “OMG” (2010) further boosted the hashtag. By 2011, “OMG” was officially added to the Oxford English Dictionary.

Cultural Impact

#OMG bridged decades of slang evolution — from texting abbreviation to hashtag to spoken expression. It demonstrated how social media formalized and legitimized internet language. The tag’s endurance shows that the simplest expressions often have the longest lives. #OMG was part of a cluster of exclamation hashtags (#WOW, #LOL, #WTF) that created social media’s emotional shorthand. The expression became so mainstream that it lost any sense of informality — grandparents text “OMG” now.
