Cách sử dụng
The expression "what the heck!" is used when you want to show surprise or frustration, but without using a strong swear word. It's a more polite way of expressing your confusion or disappointment. You can use it when you are surprised by something unexpected, or when you don't understand something. For example, if you see someone wearing a very strange outfit, you could say "What the heck are they wearing?" Or if you make a mistake, you might say "What the heck did I do wrong?" It's a casual expression that you can use in many situations to show your emotions without being too strong or offensive.
