Meaning:
This word literally means natural stupidity in japanese. Also, it means idiot, stupid, dumbass, and is used to describe a very forgetful person. It can be used in a variety of different ways, as a noun, and an adjective.

History:
This word came to be around March 2004, when a student called Yu Eric "Tenbo" Shimizu that goes to St. Marys International School in Tokyo Japan started to be very forgetful. He didnt realize that someone took his lunch box, and when some of his classmates asked him if he didnt forget something, he said "Oh No! I forgot my tomatoes!!" (soo random of him to say that), and he didnt realized that someone hid his lunchbox. From then on, he started to do other stupid/forgetful things, so the name tenbo was made.

Tenbo comes from 2 different Japanese words. Ten comes from tennen, which means natural. Bo comes from boke, which means stupid/forgetful/idiot.

Yu! Don't be such a Tenbo!!

Eric is so tenbo like.

Oh my god, Yu!! Your such a Tenbo!!!

Whale

In sales terms, a whale is a prospect that is significantly larger than an organization’s average customer.

Whales are large and extremely difficult to close. Due to their immense size, they are highly sought-after.

A whale is typically identified at first by a whale hunter on the sales team, but often requires cross-discipline participation in order to close; this includes assistance from operations, engineering, creative, client success, and business development teams.

"Shit...the sales director chewed me out on the sales call this morning. He's totally pissed that I have nothing in my pipeline. I've been focused on this one whale for so long that I haven't had time to prospect for normal-sized deals."
