use this term to further aggravate someone who is already excessively angry for unimportant reasons; personal amusement comes from watching the Grumpelstiltskin become more angry and frustruated upon being called this name
Sally(angry and irrational): OH MY GOD! Someone ate all the Special K! I'm gonna f'n kill someone! All I wanted all day was my fucking cereal! I HATE THIS!!!
