Answer- Hyperbole
Explanation-
- The difference between hyperbole and personification is that hyperbole is (uncountable) extreme exaggeration or overstatement; especially as a literary or rhetorical device.
- Personification is a person, thing or name typifying a certain quality or idea; an embodiment or exemplification.
In this case, the Man (Or Woman) is exaggerating the fact that his Suitcase weighs a lot; not identifying a Idealistic characteristic in an In-animate object.
