A common abbreviation for Mimosa Hostilis Root Bark. MHRB contains DMT; the most potent hallucinogenic drug known to man.

Since DMT is rarely sold, most psychonauts tend to purchase MHRB online and then extract DMT from it themselves using lye (drain/oven cleaner) and naptha (zippo lighter fluid), among other materials.
MHRB is one of the thousands of plants/animals that naturally produce DMT (including the brain of human beings).
Gotta grab some MHRB for my extraction tonight.

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."
