dumbar number 

The dumbar number is the number of participants in a conversation beyond which it becomes counter-productive.

The number is unique to every conversation. Some conversations have a dumbar number of 5 while some can go up to double digits depending on the mental stability, social intelligence and epistemic humility of the speakers.

Not to be confused with Dunbar’s number, which is the maximum number of social relationships a person has the cognitive capacity to maintain. So while Dunbar’s number poses a challenge to scaling trust and social cohesion in increasingly large groups, the dumbar number poses a challenge to scaling rational discourse in increasingly large conversations.
I’m leaving, this conversation is way past the dumbar number.

You’re so dumb, you lower any conversation’s dumbar number to one by joining it.

Man, I wish we had social media that increased the dumbar number across the board.

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."
