A state of being unable to remember seemingly simple things such as keeping appointments and returning phone calls.

While occasionally a natural condition for some people, it is most often a temporary state triggered by excess stress and/or a lack of sleep. It should not be considered an accurate indicator of a person's intelligence.

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."
