Will I get in trouble for prank calling the cops on the weekends ?

Do it from a pay phone and say there a beautiful white woman being chase by 4 black dudes with machetes

Yes.

It is a crime to make a false 911 call. Depending on the facts of the case, a fake emergency report to 911 could be charged as a misdemeanor or a felony. Per Penal Code 148.3, it is a crime to:

Report or cause a report to be made,

to certain government agencies,

that an “emergency” exists,

knowing that the report is false.

An emergency report is any condition that results in, or could result in:

response of an emergency vehicle, aircraft, or vessel,

the evacuation of any area, building, structure, or vehicle, OR

activation of the Emergency Alert System.

A person who reports a false 911 emergency is guilty of a misdemeanor if they know that the report is false. The punishment could be up to:

one-year county jail and a $1,000 fine.

A false 911 emergency call is a felony if the person making the call:

knows that the report is false,

knows or should know that the emergency response is likely to cause death or great bodily injury, AND

great bodily injury or death results due to the false report.

The punishment for a felony conviction under this law could be up to:

three years county jail and a $10,000 fine.

A person convicted of making a fake 911 call is also liable for the reasonable costs of any emergency response.

lemme guess:  if you grow up you'll vote for the trumpster, right?

DO NOT CALL THE POLICE LINE!!! Always prank 911 operators as they are not actual police officers. thus you can not get in trouble

not very funny because they can found out where you live and have you put in jail. 

You will get in trouble for prank calling no matter what day it is.    

If you were doing that, you would already BE in trouble. They can locate someone pretty quick, even when using a disposable or public phone.

No, keep doing it.
