There is that one annoying kid in class and you just can’t think of anything else to call them because they are that much of a twat. Why not just call them a twanner then they are a twat and a tool. And it’s much easier to say twanner instead of twat and spanner.
“Miss there is homework due in and by the way somebody in this class said a swear word I think you should keep them all behind”

“Mate she is such a twanner man”
