Headlock and mouthwashing

[Godoy._.]

I've been trying to understand and look for the relationship between mouthwashing and the song headlock for a while now. I've looked at the lyrics and seen about the song, but I haven't found any similarities (in my opinion). Could someone tell me what the song headlock has to do with mouthwashing?

the song is good for fanart edits and some of the lyrics kinda vaguely fit with the "take responsibility" theme (specifically the verse with "I'm walking, you've been hiding
And you look half dead half the time"
