Excuse me, but I was wondering about the word ''Electroshocktheapy'' what does it mean?

Step 1: Google

Step 2: Type "Electroshock Therapy" into the search bar.

Step 3: Click "Google Search."

Step 4: Look at the results.

HINT: Wikipedia is usually an all right source for quick and fairly accurate information.

Or the quicker way: Let me Google that for you...
