I'm gonna Gronk you up!

A deadshit, a suck-up, a person who has nothing going for them, a person who refuses to face reality, a bludger or a scab, a pretentious person, a rich mummy's or daddy's boy, a stupid person, a dense person or one who does not care about the opinion of others, when they are right.

Originated in Lane Cove Shops, Sydney in the late 90s and spread rapidly...

People who are up themselves. Snob businessmen.

Lads; ad lays (pig latin).

Teenage kids who refuse to grow up and cant see past there own hard cunt attitudes.

A person who does not care about themselves enough and has low self esteem.

Stupidity for the sake of a non-humorous laugh, usually between close mates; a dickhead.

Dense; someone who does not get it!

Lane Cove Slang.
"Look at that gronk lad scabbing cigarettes for spin - what a deadshit!"


"Can I borrow some money?"

"You never pay me back"

"I will this time... I promise man..."

"Fuck off gronk!"

A Gronk is an unusually large woman. A Gronk need not be fat (though most are) Often they are the tall gawky daughters of Norse races. The average ratio of Gronks to fit women is about one-in-four, per party. Gronks are often Wingwomen, allowing no girl in her group to stray and talk to any men who do not also chat up the Gronk herself.
The Gronk is often loud and a big joker. Asserting herself into conversations and loudly making jests in the hope that men will notice and forklift her off to bed.
I couldn't get close to Mandy last night. That big Gronk at the table wouldn't let me near her.
