a term used by someone who is so overcome with anger that all they can think of is a combination of profanity in the form of "stupid jerk ass tits face", mostly heard when something unexpected happens.
"hey dude" "hey what's up?" "i just slept with your mother and girlfriend all week while your were gone and got them pregnant." "what?!? you, you, you "stupid jerk ass tits face"!!!"
Short-hand for the word floccinaucinihilipilification, meaning the estimation of something as valueless (encountered mainly as an example of one of the longest words in the English language).
