Walloon language
The term "booyah" may be a variant of "bouillon". It is thought to have derived from the Walloon language words for "boil" ("bouillir") and "broth" (bouillon). The spelling with an H has been attributed to phonetic spelling by Wallonian immigrants from Belgium. The "Dictionary of American Regional English" attributes the term to French Canadian immigrants; others attribute it to a derivation from the Provençal seafood dish "bouillabaisse".
