There is a lot of madness and competition in Fall Guys: Ultimate Knockout. Most of the time, you will find yourself in everything that is happening in the eccentric littleries of the competition, and a particular strategy of many players is to attack another to remove them from the card. A realization in the game is called Fall Bae and forces you to share a hug with a Fall Guy.
What the realization involves is that you have to hang on to an opponent in the middle of a match. The person can try to move away from you, but the result is probably to prevent them from reaching the end of the game or jumping from a rim to fill a gap. The realization specifies that the capture must be a hug. When you catch them, they should not move as freely as without your catch.
Once the realization is completed, you must also ask them to return the socket. It is easy to finish this when another member of the group plays the same game as you, so if you have a friend, take him and ask him to do the same for you and that should appear. It’s a little more complicated when you play alone, because the person you catch is probably more focused on fleeing and not trying to turn around. It is a fairly fast achievement, however.
