gush over someone or something
1. Lit. [for liquid] to flood over someone or something. The floodwaters gushed over the farmland. The hot soup gushed over the cook as the huge pot tipped over.
2. Fig. [for someone] to heap praise, flattery, and compliments on someone or something. Aunt Mattie always gushed over us children so much that we dreaded her coming. All the guests gushed over my beet salad.
