"Fugg my doot" is a meme which originated from 4chan's darkest hole, /b. the OP of a thread declared that whatever post got trips at the end of their post id first would be forced into a meme, regardless of whether it was a picture or text. Sometime into the thread trips were achieved with the text reading "Well Fugg my Doot." This phrase was immediately picked up and is paraphrased as simply "Fugg my Doot" and other forms. The original phrase and its many paraphrased forms have since begun spreading to other threads on the site as an expression of surprise or disappointment and has been inserted to other meme formats such as:

>not fugging a doot" ,"Op enjoys being fugged in the doot" ,"Fug Life" and "beep beep on my way to fugg your doot."
