The accidental replacement of correctly spelled words in a sentence (or serious situation) with ghettoized words or slang, sheerly because you are used to it. Often leads to awkward or uncomfortable situations.
Example 1: "I'm deeply saddened by the passing of your friend. He was like ma brotha. Wow, please excuse my ghettypo. I'm sorry for your loss."
Example 2: "As you can see, stocks have been rising steadily and should soon climb OFF DA CHAIN!...I mean off the charts. Damn my ghettypos!
