The "ch" sound is represented by the IPA symbol for "ʃ" (as in "sh" in English), followed by the "i" sound, represented by "ɪ". The "bougue" part is pronounced as "buɡ", where the "ou" represents the "oo" sound and the "g" is pronounced normally. With this information, the spelling of "chibougue" becomes more understandable.
