There's a lot of madness and competition in Fall Guys: Ultimate Knockout. Most of the time, you get caught up in all the wacky antics of the competition, and a particular strategy of many players is to go after another to get them off the map. One achievement in the game is called Fall Bae and requires you to share a hug with a Fall Guy.
What achievement entails is that you have to hang on to an opponent in the middle of a game. The person may attempt to move away from you, but the result is likely to prevent them from reaching the end of the game or jumping off a ledge to close a gap. The realization clarifies that the capture must be a hug. When you grab them, they shouldn't move as freely as they would without your grip.
Once the achievement is complete, you must also ask them to return the plug. It's easy to complete this when another party member is playing the same game as you, so if you have a friend, grab them and have them do the same for you and it should appear. It's a bit trickier when playing alone, as the person you're catching is probably more focused on running away from you and not trying to hug you. It's a pretty quick realization, though.
