Hollister - "ill kill him ill kill him"

i was in hollister today and i heard this song and by the time i checked the screen it was gone. it was a male group singing about killing someone.. some things i remember were
" when he's with you at night" (?)
"ill kill him ill kill him"

its driving me crazyyyy! does anyone know what it could be?

it sounds like
"crack my heart" by Josephine Collective
