Morphology

bum + chum

Although 'chum' clearly means a friend, the element 'bum' has several unrelated senses (e.g. buttocks, a vagrant, or a jocular intensifier) and does not transparently signal closeness. The compound is a playful, regionally marked idiom meaning 'very close friend' and this specific sense cannot be reliably derived from the parts by a B1 learner who has only seen the constituent words.

Etymology

The informal phrase bum chum may come from the picture of a friend who is always right behind you: bum means the back or bottom and chum means friend. That's why it came to mean 'a very close friend'.
