Safaree Samuels is seething with anger, enraged that his ex Nicki Minaj would dare dispute his writing contribution to her songs.

Safaree was leaving LAX Wednesday … and he does not back down, despite getting trashed by Nicki during a concert Tuesday night.

And he thinks Meek MIll and Nicki need to stop ragging on him and worry more about their shows. Translation … “Get off my d***!”
