A spider with only seven legs, born on a leap year. This spider's mother was cursed by a russian witch by the name of hilda. A tnecniv can't eat insects and can only eat its own web. This spider can only die if it is eaten by a spider of its same species in Topeka, Kansas. When it is eaten, the cannibal spider will inplode, never to be seen again. Seeing a tnecniv will cause extremely bad luck, unless you give it a spider leg, then it will give you extremely good luck.
Guy1: "Dude, I'm scared, i think i saw a tnecniv yesterday, but I didn't have a spider leg!"
Guy2: "What?! Thats super bad luck! I don't think we should be friends anymore, for my own sake."
Guy1: "Fuck you dude."
