where do babies come from?* - melanie martinez lyrics

[from the snippets]
do they come from rainbows and love?
mommy, mommy tell me please
where do babies come from, really?
they come from boys who like to sit on their -ss
they come from girls who like to grow up too fast
they come from screaming, fighting, and makeup s-x

what a lovely little mess i’ve made
i throw milk on the walls in rage
oh i’m trying to just forget the pain
