How Do You Spell WAST PISSED OFF?
Pronunciation: [wɒst pˈɪst ˈɒf] (IPA) 
The phrase "wast pissed off" may seem like an archaic and misspelled version of the phrase "was very angry," but it actually reflects historical English spelling conventions. In IPA phonetic transcription, "wast" is pronounced /wɑst/ and is the past tense form of the word "be" in the second person singular. "Pissed" is pronounced /pɪst/ and is a past participle of the verb "piss," meaning "to urinate." In modern English, the phrase would be written as "was pissed off."
