Twigbranch Over

Twigbranch is a character in the bookseries Warrior Cats who switched clans, or the groups of people that she lived with, multiple times due to indecisiveness. When a cat changes their clan in warrior cats, this is sometimes referred to, by the fandom, as "Twingbranch-ing theirself over" to the other clan.

Person 1: "Man, forbidden romances in warrior cats are so forced!"
Person 2: "I know, right? Why don't they just Twigbranch Over to the other clan to be with their love interest?"
