Taity

Taity is a slang word for "tait" which pretty much means cheerful, gay etc.
But people mostly use it now to say I look wierd there

Taitie is slang for potatoe. Although often refered to when talking about food (e.g. Jacket Taitie for Jacket potatoe) it can also be used as a friendly form of telling someone they are a bit daft (e.g. dont be a taitie).

As far as I know this is slang in the North-east area of England.
