Short circuit

[Sarah]

A circuit formed or closed by a conductor of relatively lowresistance because shorter or of relatively great conductivity.

[Zipporah Schumaker]

To have a bit of a mental [freak out], which causes you to [respond] very erratically. Usually in a [nonsensical] way.

[Hina Muqadas]

When the medium of electrical transfer takes a shorter path back to the [power source] (cell or batteries) thus shortening the circuit, and leaving out the resistor (motor, lightbulb, [buzzer] etc.).
Short [circuiting] will drain the power source at a phenomenal rate, and is best avoided. The most commonly used method of prevention against this is the (see my definition of) fuse

[Monty]

After [skeeting] in a girls [eye], you break a [light bulb] over her head.

[Lanell]

A) When anything electronic with circuitry gets fried to a crisp because of energy overload.
When a [battery head] of a person ingests so much [battery acid] via mouth, nose, anus, dickhole or ear, that it literally fries his smartass head down to a couple tortured brain cells, giving him the IQ equivalent to a fucking grasshopper (usually hovers around 0.27 IQwith mental disorders usually come standard with 60 IQ), basically selling his soul, personality, and character to the drug gods. The mf will probably spend the rest of his life being fed by a damn robot pumping [astronaut food] through a tube that leads to his stomach, then considered a waste of human body parts and is better buried in the damn flowerbed better for plant nutrients.

[Zipporah Schumaker]

An electric current taking a shorter or different path than intended.
