the name is spelt right, maybe they spelt it wrong on purpose to emphasise the loserness as you say or maybe that's how people spell loser in portuguese. or maybe they're loose and losers, loose losers if you will. i'll find out.
is the band name misspelled; or does it mean a plural of the adjective "looser," which does not make sense, but i'm willing to entertain the possibility; or (and this one is my favorite possibility, because it would be somewhat clever) is it "loser," intentionally misspelld to magnify the implication of said name?
why do i care? well, i don't really. i'm just curious about how many points to give them for creativity.
