In February, you can flirt with a lioness from somebody else's pride every 15 minutes for the chance to earn some HS. If you're successful, you walk away with some HS! But they can slap you to fend you off within that 15 minutes and thwart your efforts, stealing the HS that you would've earned. This is a pretty fun (and fucking hilarious) feature!

There should be two flirting options: one to flirt with a lioness, and one to flirt with a king.

It works exactly the same as lioness flirting. The king of the pride (or you!) must find time in their busy schedule to fend off the flirtacious advances of a rival! Potential flavor text here.

Mechanics:
Kings would be in the pool of males to be flirted with, not sub males (since not everyone has them and some have way more than others). People would then have 15 minutes to thwap the advancer across the face. As for the whole "them not succeeding at stopping you" thing, it could be that they dodge your slap attempt and run away laughing. When it comes to the 15 minutes running out, the flavor text could go along the lines of "You were so preoccupied with your business that you didn't get the chance to slap the king that was flirting with you! Damn!" Potential flavor text for this sort of thing here.

I intended for it to function so that you cannot flirt with both a male and a female at the same time in hopes of getting double the HS. You'd choose to flirt with males or females, then wait for the cooldown. After that, you could opt to flirt with either again. It's one or the other.
In addition, there would be a toggle for you to opt in or out of having your king flirted with/flirting with other peoples' kings.
