I fail to understand how people drink coke and similar drinks daily.
Are you kidding? The sense of surging capacity, the illusion of competence . . . oh, wait, you said "Drink".
More seriously, one could easily replace "smoking", or "autoerotic asphyxiation", or "zoo porn". Humans demonstrate a Lot of behavioral diversity, so what vices we give in to are nor especially likely for others to empathize with.
@Siedge you know one thing I "fail" to understand? On the topic of screwball grammar, the phrasing of using "zero" instead of no/none. (the phrase "zero fucks" is an exception given how it's blown up in memes, carving out an idiom). But I can be a mad grammar nazi, more just for fun than getting pissy and taking on a grammar teacher tone.
