i chose her tweet on september 12th that says:
screaming BRING ME THE HALO TOP BRING ME Flips table THE flips another table" HALOOOOO TOPPPPPbirthday halo top appears* NOT THIS ONE
McCulloch states that when someone uses all caps, they are conveying strong emotion. repeating letters are also an "expressive tool" (233). the way she writes this tweet portrays the idea that she is feeling VERY strong emotions about halo top. she needs that halo top. but she does NOT want the birthday cake halo top, because duh. she's obviously meaning to be funny, but i think she's also a little serious and wants us to know that? she obviously feels really strongly about halo top, and that is nothing to joke about. she also creates this idea of an "in-joke" about how birthday cake halo top sucks. she knew a certain audience would understand her joke, so she said it. she also uses asterisks to add irony to the tweet.
however, we see her do a complete 180 in a series of other tweets, where she says "I want to fucking quit." and It's all a fucking boy's club." in these, especially in the first one, using the period at the end of the sentence conveys that she is very serious. she's not the silly, fun girl who wants halo top. something has obviously upset her to the point of using grammatically correct sentences--no capitalizing words, no cheeky comment, nothing. her tone is completely different because her tweets are devoid of effort, just like she is feeling as she types it. the simple sentence structure and complete lack of her fun, usual things shows that she is upset. overall, she seems like a smart, funny, intelligent individual who is incredibly relatable.
