Wow Mark, you sure can tell your an ex-teacher. Here lately you've helped expand my vocabulary tremendously....

1. Plonker - "dope, idiot, moron, wally, pillock, dunderhead, dimwit"
2. Plonker - "The term plonker started out as a reference to someone who was forever drunk on cheap wine (cheap wine is nicknamed plonk) this person was usually a homeless person, or poor person.
Today the term plonker is a very light hearted insult. It's not even seen as an insult, it's like calling someone a wally. It's in no way meant maliciously. You call someone a plonker when they say or do something stupid."
Definitely a much more gentile way of calling someone a dumbass....

Thanks for learning me....
