Right when you think you are safe from any battle, somebody has to run up and ruin your day -- with a frying pan. This video is not of actual PUBG gameplay, but instead about what goes on in players' heads when killed by a frying-pan-wielding aggressor.
To give the clip a bit of context, PUBG has a Battle Royale Mode where 100 players are put on a small playing field in a last-man-standing free for all. The character in this video is not about to get caught in that, and so he runs away from the battle zone. Once he's "safe", he's screwed over by a guy with a frying pan, something many players understand far too well.
