Someone on reddit asked about it. And it turns out there’s a logical-ish reason:

all of the other players pair off with their man to prevent anyone else entering into the fight … so it’s a form of self policing. 

[…] The players basically want to prevent 2 on 1, etc. fights and by finding a “hugging” partner so there’s no ganging up on one guy, even on accident. They do it because it’s fair. And it’s kind of cute sometimes.

this dog that i dogsit for is an actual angel sent from heaven, evidence:

he’s 100 lbs and so gentle i don’t need any special collar or leash or harness to walk him, ever

he was meant to be a service dog but he was too shy so he became a rescue, can u even imagine

so well behaved he waits for me at the tops and bottoms of flights of stairs until i tell him it’s okay to go ahead up/down the next flight

he somehow communicates to his dads how much he loves me bc they tell me every time i leave and they come back he’s sad ?? my son !

he knows that if it rains or snows or he gets wet he needs to wait at the bottom of the stairs inside their condo to be towel dried

he is trained to towel dry himself; i hold out the towel and he wiggles his body through it back and forth until i dry his tail and that’s his signal to go ahead and go inside

loves pets and attention but is shy so once given pets and attention basically loses his mind and rubs his face all over you while not knowing what to do with his entire 100 lbs self

always a slut for chin scratches

spots of white on chest and toes and chin

will pretend to be scary at men when they come into the house until i reassure him it’s ok

other dogs Love him bc he’s so big and so sweet and so chill and it’s fun to walk the best looking dog who is also the nicest dog while everyone around you is like “wow ur dog is so cool” like thanks i made him
