Knit Knacker 

A female who starts drama by making complete nonsense up to feel important, someone everyone knows that does this. She may be quite charming at first glance but you rralize she is a sociopath pretty quick (hopefully) depending on if others warn you about her. Most likely the ugly quiet "otaku" or "emo" girl across your class who looks innocent until you learn she is a complete psycho b**ch. She Is a literal cum bucket and is desperate to be in a relationship, she will use anything she knows about someone to get closer to an individual that she likes and pretends to have known certain people for a long time when those people

barely know her. She is knitting her own thot sweater and degrading herself more and more day by day as more people find out the f***ed up things she did to others whether it was framing them for false rape or spread complete bullsh*t around and make someone look terrible, just to make her feel 'important' or have some "attention". Literally the highest rank a thot can get to

Watch out for harley, i heard she was a real knit knacker.

Aye you heard about that one crazy knit knacker gamer girl?
