Devin Spelling
Also known as "DS", it's a form of atrocious spelling and grammar popularized by none other than a person named Devin Smith. It's most commonly used in real life, where the person has no clue how ridiculous and immature they sound due to their pathetic form of speech. It can also be used over the internet, where the person types with the intelligence of a 4-year old.
