cheese sliding off the crackers 

To go totally insane, in the same vein as losing one's marbles.

Phil threw another tantrum over a missing sock. I think he's got his cheese sliding off the crackers.

Sliving 

Invented by our Queen Paris Hilton. It's slaying mixed with living my best life.

I am sliving, sliving it, sliving my best life, sliving single.

sliding back into childhood

That slow decline in later years when many head backward, sliding steadily into an increasingly childlike mentality while often facing the concurrent loss of their physical integrity.

Oh yes, we’ve all watched her become like an innocent again, sliding back into childhood; for her, the world is new and beautiful all over again, even though she went through a hellish life that took that childhood innocence right out from under her so long ago!

Sliving 

Coined by Paris Hilton during an interview with Kim Petras, she defining it as "killing it and slaying in one word."
Also considered the new “That’s hot” which Paris Hilton’s first and was adored by many.

Due to her lack of immoral opinions and scandals, the media failed to catch this new phrase from its creation.

Often used as a combination of “Slay” and “Live” as most fans assumed she misspoke as Slay and Kill can be interchangeable so it would be unnecessary for another word to be made in conjunction, but thus deepening the “word” into a “meme”.
This is partly what makes it such a specific and needed word in today’s online linguistics

Friend: “I found this brand new top by this fabulous designer... you’ve probably never heard of them-”
Me: “of course, they’re like, sliving the industry!”

Friend: “ugh I dunno if this lipstick is to much.”
Me: “No way! You totally sliv with that colour!”
