look up any word, like wyd:
When someone mentions something that others consider to be general knowledge or previously discussed, they are often met with the following sacrastic comments to imply that it is old new:

- Man walks on moon
- Man invents wheel

This has been shortened to MoonWheel. So when someone is the victim of MoonWheel, they have been Moonwheeled!
Dude1: Het guys, did you see that Apple are release a new iPhone?
Dude2: MoonWheel
Dude3: OMFG LOL!! You've been Moonwheeled!!!
