Literally is an barutoanderusu. It's been romanized all sorts of weird ways. Valt Andres, Bart Anders, and so on. There is only a little solid info about what this name is supposed
to mean:
1) The kanji for "barutoandersu" read "tsuki no monshou no ken"(the
Sword of the Coat of Arms of the Moon) a "tsuki no monshou" means that the crest or the coat of arms on the sword is a moon.
2) According to ryuuen, in the O-fen encylopedia or something, his name is
translated to mean, "always something else" or something like that.
3) Ryuuen posted to a JP BBS asking how to romanize the name, and they replied that they thought it was based on a German folktale.
4) It's Baldanders(Bahlt-ahnderz). Split up into two words, bald and anders, it means "soon" "something
else/different". Baldanders is a... thing... from a book by Hans JakobChristoffel von Grimmelshausen. It's called "Der Abenteuerliche Simplicissimus Teutsch", and it was written 1668-1669.
5) Baldanders changes into a bird and flies off, and the hero wonders what kind of devilish magic he taught him, and whether Baldanders really wasn't the devil after all.
6) Baldanders was a magical creature who specialized in transformation and
probably had some tricks up his sleeve.
A term with a stupid origin. The word "balt" supposedly has no meaning, but when combined with the name "Mickey" (based off of Mickey Mouse) it is a multi-use word/term for any situation.
It could be used to express your mood, describe something, or just randomly say it for no reason at all.
A word of caution;
No one will know what you're talking about 100% of the time. Make sure to do it anonymously or with friends as to not come off as an insane person.
Jim: "It is going to be super busy in the store today."
Bob: "Yeah and we have a huge work list to get done."
Jim: "and a ton of customers to take care of, maybe Brad can help us out with the customers while we get the work list done."
Bob: "Dude, Brad went home early said he needed to cut hours today."
Jim: "are you fucking kidding me man? We are totally Getting the Baltes in here today!"
Don't confuse Latvians and Lithuanians with Russians, since Balts are not related to them - be it ethnically or culturally, and most of the younger generations don't even understand Cyrillic.
much like in the situation where you would say "balls" you can instead replace this word with "balt". Often shouted by the Southern British in an nightclub where the girl they are trying to get with rejects them or an unbelievable fuck up has occurred.
