As someone who\u2019s dealt with acid reflux my whole life I just realized that\u2019s what \u201cjust threw up in my mouth a little\u201d was invoking. \u2018cause it was used as like \u201ca reaction of disgust\u201d but I just thought of it as a meaningless bodily curiosity like hiccups
I dunno to rescue it maybe there\u2019s some sympathetic/parasympathetic nervous effect on muscle tone involved, like how pissing and shitting are invoked as markers of fear
When I was young I used to think of it as \u201cburping SpaghettiOs\u201d because it had similar texture and acidity
