It means BYOB but fun is substituted for booze. This is done because alcohol often starts the fun. The lone Sober person at a party does not usually have any fun.
Fun is also substituted as a code word so that minors don't have to worry about adults figuring out what is going to go on at a party.
The fact that it sounds nerdy and innocent makes it ironic.

Bring your own fun to the party saturday.
Should have brought some fun.

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."
