I Bet He's Thinking About Other Women

I BET HE'S THINKING ABOUT OTHER WOMEN; IN THE SONG TWO WEEKS THE GUY SAYS "I'M THE KINDA GUY THAT LAUGHS AT A FUNERAL. DON'T UNDERSTAND WHAT I MEAN? WELL, YOU SOON WILL." IS HE LITERALLY THREATENING TO KILL SOMEONE I CARE ABOUT? BECAUSE TO GET ME UNDERSTAND WHY HE DOES LAUGH AT A FUNERAL THERE WOULD HAVE TO BE ONE. AND NOT JUST A RANDOM ONE BECAUSE I MIGHT NOT ATTEND. AND IT COULDN'T BE MINE BECAUSE I'D BE DEAD AND DEAD PEOPLE AREN'T CAPABLE OF ACQUIRING NEW KNOWLEDGE.
