The funniest most fularious fucking word you'll ever read.

When in an argument with some jack ass call him/her a krustamafuck and he/she will burst out in laughter, allowing you to sucker punch him/her.
Jackass: Who in the FUCK do you think you are taking MY parking spot?!
You: Piss off krustamafuck!
Jackass: *breaks out in laugher*
You: *punches jackass in the gut*
