시곗바늘이찔러와 = 시곗바늘이 찔러 와 = The hands of the clock (seem to) prod/prick me. (It sounds like a metaphorical phrase about being stressed because of time) 시곗바늘 is a compound noun made up of 시계(clock) and 바늘(needle, hand of a clock). The additional ㅅ is a phonetic grammar element called 사이시옷(connecting ㅅ). It is added when a pure Korean word ending in a vowel combines with another noun to create a compound noun, to make the pronunciation natural (it effectively adds the [t] sound to the syllable and strengthens the next syllable). Here are some examples of 사이시옷. - 잇몸(gums of the teeth) = 이(tooth) + 몸(body) - 시냇가(shore of a stream) = 시내(stream) + 가(edge, periphery) - 이삿날(moving day) = 이사(moving) + 날(day) - 찻잔(tea cup, cup of tea) = 차(tea) + 잔(cup, glass) - 뒷마당(backyard) = 뒤(back) + 마당(yard)
