Onsen 

An onsen is a Japanese style public bath using volcanically heated hot water from the ground.

The term onsen is often used in the Japanese language in reference to the bathing facilities surrounding hot springs.

Onsen, when translated into English means 'hot spring', which can lead to confusion and miscommunication.

After watching the monkeys in the hot spring, do you want to go to an onsen?

Sudden Onset Autism 

Sudden Onset Autism, or S.O.A for short, is an extremely rare condition of unknown origin. Development of this disease is both abrupt and severe. As of now, the pathogenesis and mode of infection have eluded even the most qualified of research teams at Harvard, Hopkins, and Yale. Some have suspected that transmission occurs through contact with an infected person, especially prandially. There is still hope for a cure, although we may be decades away.

Infected Person: Hey man, let's go grab some lunch
Healthy Individual: what?! It's 3 in the morning. What's wrong with you
Infected Person: Well... it's lunchtime somewhere!
Healthy Individual: Oh God, you have Sudden Onset Autism... Please go away from me!
