کاملا بدرد نخور
۱. کار یا روندی که اصلا تاثیرگذار نیست و پیشرفتی نداره
Yesterday's meeting was a dead loss - nothing was decided
۲. شخصی که موفق و سودمند نباشه
I was a dead loss at languages at school
John was a dead loss - he just stood there and did nothing
۲. شخصی که موفق و سودمند نباشه
خسارت کلی
بی استفاده
