U+02AC "ʬ" Latin Letter Bilabial Percussive Unicode Character

U+02AC "ʬ" Latin Letter Bilabial Percussive is a phonetic symbol used to represent a sound produced by bringing the two lips together sharply to create a percussive noise, essentially a lip smack, without any accompanying vocal cord vibration or airflow typical of standard speech sounds. It is part of the International Phonetic Alphabet (IPA) extensions and is occasionally employed in the transcription of certain extralinguistic phenomena, such as the sounds used in beatboxing or in rare linguistic contexts where a bilabial percussive functions as a speech sound.
