Like "cock blocking" but instead, it's a friend that, for whatever reason keeps the other two friends of a three friend group from becoming close.
*3 friends get into fight, 2 have been hanging out*
Best friend #1: "Why didn't we become bestfriends before now?"
Best friend #2: "I think (insert friends name) has been buddy blocking us!!"
Friend: "Oopsie." 😳
