ReplaceInternetSlang - Convert Internet Slang into sentences

ReplaceInternetSlang is a function that converts Internet Slang / Jargon into readable text. The function has been designed in a manner so, say your string contains "lollies", it won't detect the lol inside of the word.

  • Detects multiple occurences of the same word.
  • Advanced detection of whether the occurence was a word or not.


  1. Create a new class, call it InternetSlang.vb.

To call the function from your main form, or any other class for that manner, you can do so like this:

MsgBox(InternetSlang.ReplaceInternetSlang("rofl lol"))

I used a MsgBox for the purpose of the example, as the function returns the string representation of the edit.
