The mother was very angry when she caught the narrator sneaking texts at the dinner table.
Step-by-step explanation:
The most likely meaning behind the example of hyperbole is that the mother was very angry when she caught the narrator sneaking texts at the dinner table. Hyperbole is an exaggerated statement or claim that is not meant to be taken literally. In this case, saying that the mother's head was going to explode emphasizes how angry she was, rather than indicating any physical harm.
