The way I heard it was put the letter 'b' in front of the vowels in the words so taking Brother Moss's sentence, it would be:
Mboss lbikbes fbootbball.
Trust me bro abs, you dont want to learn it, it's pointless and rude because when you learn it and talk with your friends, as bro Moss said, you do it so nobody else understands. And one of the sunnahs is that when there are three people in a room then when two people talk they should talk in a language the third understands so he/she doesnt feel left out. (If you understand that
)
Can you tell that I never actually spoke it?
