“Tèt kale” is when the person does not have hair on their head. It can also be used when someone is doing something boldly, with confidence. That particular character, in this case. is acting “tèt kale”.
But if you change the position of these two words, you will have “kale tèt” which can be the fact of cutting all the hair on somebody’s head, but also someone being an abuser, someone who is using astuteness to take what someone else has. This is mostly used when an individual fakes to love somebody to take advantage of him/her in a relationship.
There is no problem to be “tèt kale,” but it’s wrong to be a “kale tèt”.
