for example, in rush hour 1, one of the Asian guys, I forget his name, throws a napkin at Chris Tucker and says, "wipe yourself off, you're bleeding". Towards the end of the movie, after Chris Tucker kills the same guy, he throws a napkin at the Asian guy's corpse and repeats the line, "wipe yourself off".
this happens all the time in movies and in real life. there has to be a name for it
