1. To mention that you are not sure about something.

2. To say that something is not convincing, an overreach or delusional at the worst.

“That new song is not make sure.” – “That new song is not too good.”

The phrase was popularised by a video of an interview that went viral of Goodenough Sithole using the phrase.

“Drinking this meal replacement shake and norrr maan, is not make sure.”
