To me this song is about three gay men.
The man in the white car is someone who isn't out, perhaps even still in a heterosexual relationship. He is jealous of the narrator's relation with his boyfriend or maybe just the narrator's gay friends.
He will never come out, he will never end up in a healthy relationship with another man but he might do some naughty things with other men in the parking lot.
Maybe he had a threesome with the narrator and his partner? I imagine gay men are a little bit more sexually open than the rest of us, but still the narrator need to calm his partner down to avoid jealousy.
Also the sentence about 'fruit humming' leads me to think of gay men.
