The spelling of the word "blastie" might seem odd to some, but it actually follows the rules of Scottish English phonetics. In IPA transcription, "blastie" is pronounced as /ˈblæsti/. The "ie" at the end of the word indicates that the vowel sound is pronounced as a short "i" (as in "bin"), while the "a" in the middle is pronounced as a short "a" (as in "cat"). In Scottish English, this spelling is commonly used to describe something that is unpleasant or contemptible.
