fucking + ignorant.
To be so ignorant, people must say "fucking" infront of it to truely capture how dense one is.
"Fugnent" is born out of a need to say it even faster, so as not to dwell on the clueless person.
fugnance: the act or being fugnent.
"That Tiara-girl, she's so fugnent, she doesn't even realise no one likes her!"
"How fugnent are you, Matt? You can't name yourself on Urban Dictionary!"
"Racists are so fugnent."
