Bruh u got it wrong. Abdi warsame reer Abti are Sacad like Ahmed hirsi."Was I not your uncle yesterday. I won't lend you support based on qabiil premises".
You need a little background info. Ahmed guy is referencing to "uncle" in the sense that he is married to Warsame's clan associate. Depending on the sex of the relative you either are an Abti or Adeer to someone. I hope I explained it.
It appears that Warsame approached Ahmed and said to him, in a endearing way "abti ". He was probably looking for support.
