...when you want to act or look all cool by showing off your amazing skills for singing a song, and then this happens:
a) you get all excited and sing at the wrong part. ouch. awkward silence.
b) you sing the wrong lyrics and have to kind of mesh it into the real lyrics and be all like.. yeah, i meant to do that, or just stop quiet in your tracks. there's that awkward silence again.
don't you just hate that?
