this word sounds like its insulting, but it means literally nothing. you can use it as a replacement for cunt or fag or whatever your heart desires. it's also effective to use around children because they'll pick it up and use it over something more insulting. dunno what tf it means though.
child: "do you have games on your phone"
you: "go away you little quank"
child: *cries*
Pretty much any task that takes effort to do
School: we're doing bag packing for charity
Half the students: Ahhhh trek
