Verb / Noun - To Telsi tell-see often mispronounced by math teachers, this word derives from the Serbian word teslah. Which literally means to generate very high voltage, low current, high frequency electricity and pass it through a human being's torso region. This causes the human in question's internal organs to be melted at a temperature of approximately 30,000 °C (54,000 °F), hot enough to fuse silica sand into glass. This is often considered to be the opposite of what is good but telsis are usually, smart awesome and irresistibly beautiful.
