From The Awl:
Of course, there are instances when "argh" is a perfectly acceptable word, like when Batman is rabbit-punched by a hired goon (Argh!), or a sea pirate loses his entire savings in an elaborate pyramid scheme (Argh!), or when the main character in a Serbian knockoff of Cathy, named Gathy, finds out she’s scheduled a date on the same night as an old flame’s funeral (Argh, argh, argh!). But during sex? Argh.
Don't miss the post about the series' use of synonyms, either. Good stuff.
