When you need a strong hint that something's off, like in a crime novel where the culprit uses Pentobarbital for their evil deeds, 💊🔪💀 is the perfect combo - it's like the emoji version of a red flag. You could use it in a text with friends discussing a dark movie or TV show where the plot just took a drastic turn. For instance, if someone messages just found out the main character's going to off themselves with an overdose of Pentobarbital, this emoji combo will add the right amount of drama to your response.
