Danny's line from "Grease" showcases his physical bragging and indicates attributes of machismo or overconfidence.
Step-by-step explanation:
Danny's exclamation, "I don't know why I brought this tire iron! I coulda yanked these babies off with my bare hands!" from "Grease" allows us to peek into his character and his tendency towards bravado. This line indicates that Danny sees himself as physically strong and capable, almost to the point of not needing tools for tasks like removing car tires.
