Imma be real with you chief
When you are about to tell a friend something that they should never repeat in front of anyone else under any circumstances.
"Hey Drake, Imma be real with you chief, I think Travis is so fucking whipped by his girlfriend."
"Word, I respect that"
"Word, I respect that"
Imma keep it real with you chief
You say this to your homie before you keep it real with them
"Imma keep it real with you chief, your girl is a hoe"
