How about they just call it, you know, "clicking jaw"?
ماذا إن دعوه بـ" طقطقة الفك " ؟
Buster's jaw clicks when he eats.
يَنْقرُ فكُّ المحطّمِ عندما يَأْكلُ.
They made him stop eating after midnight, and he's hungry, and he's in a foreign land... and his jaw is clicking, and he's scared.
جَعلوه يَتوقّفُ عن الأَكْل بعد منتصف الليلِ، وهو جائعُ، وهو في a أرض أجنبية. . . وفكّه يَنْقرُ، وهو خائفُ.
