Onehunga

A small town in south-central Auckland. Filled with hory Maoris and Islanders alike. Lacks funding, trash facilities but at least there's a countdown. Prime spots for hookahs at depot and the dress smart carpark. Enjoy listening to all the crackheads shouting about god on a Saturday and broke asses who ask you for a dollar.

"G talking shit? Hookahs on Onehunga?"
"Yo come then cunt"

Onder 

To overtly use proper grammar, really long sentences, and pompishness in day to day life.

Brian: "Hey dude let's smoke a blunt"

Onder: "I do think that is such a terrible idea, and thus, we should not do such a thing. But should you wish to do so, you do understand that you would be breaking the law and have a chance of being imprisoned? I beseech you to not smoke such cannabis in my face"

Brian: "wtf dude why are you so onder?"

Onder: "I am deeply offended at your usage of such profane language. Please abstain from asking me with such brash and terrible manner."
