Okay, I know this is perhaps nitpicky, and I know I'm a broken record on this. But ain't nobody a Coke addict. Well, okay, people are coke addicts, but nobody is addicted to Coca Cola.But then again, I'm a Coke addict so I'm probably biased.
Two problems with this: it's inaccurate and it's... is ableist the term I would use here? Sure, ableist.
Inaccurate: Even if someone was a compulsive enough user of Coke to have withdrawal symptoms if they quit (headaches, etc.), physical dependence and addiction are two different things. Addiction means that no matter what the horrendously awful negative consequences are, you cannot stop using a substance/engaging in a behavior. Using the term addiction incorrectly perpetuates this problem.
Ableist: Using the term addiction this way makes light of a debilitating, lifelong condition (though it can be managed). To me it sounds similar to using terms like "schizo" or the R-word lightly.
I know it's a common phrase, especially in Utah Mormon culture, but this is why it bothers me.
