'Bum-ish' Meaning something is not up to your or others standards, and if something is 'not good' or 'bad'. It has been used alot in the younger generation as sort of a light way to let out your inner feelings. Or in other words, a censored swear of sorts. This could also add comedy to the situation your in making the thing that's bumish less, well, bumish. As it uses the word 'bum' which may be entertaining or funny to the younger people.
You could use it like: "That test sheet was bumish" instead of: "I didnt enjoy that test sheet." You would not say: "It was so bumish.", just: "It was bumish."
