The word mig is perhaps among the most useful terms in the multiverse. Originally invented by hovenbeet when some played bagpipes at him, it has since been used in almost any imaginable. The term is typically used to give some sort of factor of irritation, however another more common use is when one forgets a word and needs a substitute. For example, a man who forgets what the name of pomegranite jelly is, he might say "Can you please pass me the, erm... mig"?
The term mig is also useful in the sense that it can be used to substitute a very rude word, and thusly you can shout it at your broken toe without getting rude looks and some weird guy squealing "Don't swear"!
