What does wally mean?
Wally is an informal British word with two strikingly different uses. As a noun, it refers to someone considered stupid, ineffectual, or particularly bad at a task: a forgetful person might be called a wally, as might someone who performs badly at sport. This use can sound seriously insulting, although it may also be humorous among friends or used teasingly. As an adjective, wally means excellent, enjoyable, or enthusiastically approved of, as in a statement that a performance or meal was absolutely wally. The noun is especially associated with Britain and other varieties of Commonwealth English, while the positive adjective is chiefly a modern British usage. Although Americans may understand the word, it is not common in general American usage. The contrast between its negative and positive senses makes wally especially memorable: the same word can condemn someone as inept or enthusiastically praise something.

Etymology of wally
The slang noun is documented from the mid-19th century, but its precise origin is uncertain. One proposed derivation connects it to the familiar name Wally, itself a diminutive of Walter, though this explanation is not certain. The later positive adjective meaning excellent is modern British slang and developed as a separate sense or usage from the older insulting noun.
How wally is actually used
