A more thorough explanation:

A holdup, also known as a stickup, is a type of robbery where the victim is threatened with weapons such as guns or knives. This type of robbery is considered to be very dangerous and can result in serious injury or even death.

For example, if a person walks into a convenience store with a gun and demands that the cashier give them all the money in the register, this would be considered a holdup. Another example would be if a person is walking down the street and is approached by someone with a knife who demands that they hand over their wallet.

These examples illustrate the use of weapons to threaten the victim and take their belongings. It is important to remember that if you are ever in a situation like this, it is best to comply with the robber's demands and try to stay calm.
