haz
Haz is internet slang for "has," originating from lolspeak and image macro culture: I can haz cheezburger?
The deliberate misspelling mimics childlike or animal speech, typically in captions imagining what cats or other creatures might say.
Now used ironically or nostalgically in online contexts.
