A painful white, or sometimes red bump in your mouth. You might get them on the inside of your lips, the inside of your cheeks, or anywhere in your gums. They're normally caused by putting something dirty in your mouth, such as keys, or simply putting money in your mouth (nickles, quaters, dimes etc.) or even not washing your fruits! These things usally last for 1 or 2 weeks. It heals better if you don't put any treatment on it. But try advil to reduce the pain.

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."
