Facebook obligate friend
When someone sends you a friend request on Facebook and you feel like you have to accept it because you're too lazy or too scared to say no. It's like being trapped in a friendship prison.
My cousin sent me a friend request. I accepted it because I didn't want to be the weird one who ignored them.
My ex sent me a friend request. I accepted it because I thought I might need them for emotional support later.
My neighbor's dog sent me a friend request. I accepted it because I was too tired to think straight.
