Grumpelstiltskin 

a play on the name of the dwarf character in the classic Grimm Brother's fairy tale which is used to label someone who is pissed off for an insignificant reason

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!!!

Sarah(calm and cool): Simmer down, Grumpelstiltskin.

Sally: Fuck you! I hate you, you cock-juggling thunder cunt!...(continues to yell and scream and hate on Sarah)
