SU is short for Super Unicorn. This one of a kind creature has been living for the past six centuries and knows about everything (except computers because he was busy preaching philosophical lessons when computer science was advancing). Many people believe that SU does not exist but historical sightings reveal that the creature may indeed be living among us for a very long time. SU was last spotted in the country of India, more specifically in the state of Maharashtra, according to certain unreliable sources.

Anecdotal evidence suggests that this creature is very similar to male human beings in terms of physical appearance.
He is known to possess certain powers which include Victory Dance, Intellect Beam, Emotional Torture, and Future Sight. He is also known to be a very wise and mature creature who offers advice to anyone who asks for it (and anyone who does not).
SU is known to have made and lost many friends in his long life so he appears to be rather recluse at times. He has been seen hanging out with turtles and tortoises often. The slow animals live a long life, very much like him, which enhances their friendship.
SU is known to be a social creature with anti social tendencies. To remain hidden from the prying eyes of the world and still maintain his original identity, he takes names with initials S.U. and tries to blend in with humans. He makes sure that he does not develop deep and strong bonds with most people because he is sure to outlive them.
Girl 1: That guy is definitely SU. I know it, I can feel it. I wish he noticed me.
Girl 2: I know, right? I wish SU would notice me too but we can never be so lucky.

Word of the Day on October 4, 2026
British slang for a scientist or technical expert, esp . when the speaker is not certain of the expert’s specific field of study. Not necessarily derogatory, but typically used by persons without a technical background. In the US, the equivalent would be “egghead”, “squint”, or “geek.”

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.
According to the boffins downstairs, the murderer used a serrated blade.
