There really isn't a definition. You might of heard of the word Flagnoff.
That word is false.
It was a school day and I was really pi$$ed that a girl was being jerk-ish, so when my best friend asked me what's up I said: Nothing, but (that girl) is just being a flognoff.
Well teacher's like to give green cards to kids who swear.
So pretty much it's a substitute for a swear word.
Why is there two Flognoff's but spelled differently?
Well because after I started to say Flognoff more, other people started saying it more. Like my best friend. Thing is, I didn't expect her to pronounce it "Flagnoff" and Urban Dictionary it. When I noticed how much she was kind of rubbing it in that it was pronounced her way so it was her word, I got really pi$$ed. So I'm making sure everyone knows that Flagnoff is not the original word.
So why didn't you do this before?
Because I didn't think that having invented the word meant a lot until my friend made it it.
Oh my flognoffs!
You're such a flognoff!
Flognoff my life.
She's such a flognoff.
