When a change is made to a champion, they are said to be (champion'd)

Let's start with the ones we know:

Olaf'd: To be nerfed to the ground and rendered nigh-unplayable. I hate how Azir got Olaf'd.

Sejuani'd: To be nerfed because of exceptional synergy with an item, followed by a nerf to said item. Man, Riot definitely Sejuani'd Yi when they changed devourer to bloodrazor and made guinsoo's so expensive.

Yorick'd: To be forgotten for years, get reworked to critical acclaim, then promptly forgotten again. I'm excited for Warwick's rework, I just hope he doesn't get Yorick'd.

Here's a newer one:

Taliyah'd: To be released in a weak state, given compensatory buffs while the players learn the champion's mechanics, become the dominant pick in their role, and promptly get nerfed to the back of the pack. I know he's weak right now, but I really like Ivern... I'm just worried he's eventually going to get Taliyah'd.

So... what does it mean to get (champion)'d? I want to see what you guys can come up with!
