Do some bullies bully their 'friends' and then their 'friends' bully someone else to take out their frustration?

Anonymous

I work with two colleagues that have known each other for a long time. One seems to bully the other sometimes (e. g. described him as animal to other colleagues that pees everywhere) and yet they act like friends too. I feel like the one that gets bullied sometimes seems to take out his frustration on me (e. g. Comments implying I am the main person causing a mess when I am not) but I am also his 'go-to' when he needs help/training. I consider myself patient and caring.
