Backstabbing means that instead of using screw terminals to connect wires to outlets and switches, the wire is pushed into a connector that grabs the wire inside the device. This creates a loose connection, and loose connections cause the wires in outlets to burn up and kill the rest of the circuit.

When you plug in a three-pronged plug, that third prong is providing an alternate pathway for electricity in the event of a fault. If you cut the third prong off of a plug, you defeat the safety feature. Also, adapters were designed to use the cover screw to complete a ground circuit on some older plug designs.
Why do electric plugs have holes answered?
These round bits fit snugly into the holes in the plug, which helps to provide for a more secure connection.
