Negative take on drugs (nicotine)
Wondering when a smoking cigarette in the mouth finally stops being a sign of coolness in western popculture. It's not cool, it's an addiction, nothing more. and it should be treated like that.
Imagine meeting a person you think is super cool and cute. You flirt with them and feel your heart beat faster when you're with them. You're grinning all the time and are so happy when you see them. Finally you get so close that you get to kiss those soft, kissable lips you've been daydreaming about.. and it turns out they taste like garbage bin. It literally does, honestly. Nothing cool or cute about that... Just gross and off-putting.
