The phrase "more pissed off" is a commonly used expression to describe a state of extreme anger or frustration. However, it can be useful to have a range of synonyms to avoid repetition and to convey slightly different shades of emotion. Alternative phrases to express heightened anger could include "furious," "incensed," "enraged," "livid," "infuriated," "outraged," "seething," "irritated beyond belief," "beside oneself with anger," and " boiling over with rage." Whether in formal writing or casual conversation, varying word choice can help to communicate the intensity of emotions more precisely.
