No one in America would say this. We
call the buttocks "the ass", the
rectum "the asshole", and would call a
person an "asswipe".
In America a bum is a lazy person or a
beggar, or a person of bad character.
And bum can also be used as a verb, as
in to borrow a small thing with no
intention to repay, such as "to bum a
cigarette" from a stranger.[Comment by: American Joe Rated:1/5 ]
Very bad katakana and explanation.
Katakana should be "ru-za-".
Explanation should be "ninki ja nai
hito".
Basically, a "nerd"...perhaps a person
who wears glasses and is smart, but is
not good at sports and does not get much
respect.[Comment by: Rick Rated:1/5 ]
Loser shouldn't be translated as "nerd".
A loser would be someone who is a
failure, i.e. has no money, job, or
girlfriend etc. A nerd would be someone
who is incapable of style or who is
socially unskilled. [Comment by: robert ]
