The song "Stay" by Mac Miller is about a complicated relationship that he is struggling to maintain. Throughout the song, he asks the girl to stay with him for just a little while longer. He acknowledges that she is complicated and difficult to read and is frustrated that she gives him the silent treatment in return for his questions. He also expresses how much she means to him, stating that she has saved him and given him peace of mind. Although he acknowledges that their relationship can be difficult, he is willing to make music and forget about the bullshit if they stay together.

The second verse continues with the theme of the girl playing hard to get, but he is determined to read between the lines. He also references how they binge-watched Sopranos together and how she had to come to see her freaky side, leaving him behind. The bridge expresses his intense desire for her and how he no longer wants to be polite. He wants her to make herself comfortable and wonder where she could possibly go if she leaves.

Overall, the meaning behind "Stay" is about the complexity of relationships and how both parties must work to keep the relationship going. Mac Miller highlights the struggles of maintaining a relationship, but is willing to stay with the girl he loves despite the difficulties. The song ends with a moaning outro by Paige Montgomery, possibly indicating a sexual encounter between the two.
