“I’ll deck u lad”
“Ahaha Gowan ye fat fuck”

"I'll knock u clean out"
"Gowan then"

"(You) Gowan get fucked you arse."

Gowanism examples:

"You got to get on all four's and bear crawl like a wild-ass indian"

"Buggy's gonna go through 4 hole like a diamond through a goats ass"

"Buggy's gonna pass that safety like 2 ships passing in the night"

"Sometimes when your toatin the mail John you have to find a soft spot to lay down"

I was absolutely gowaned in the gutter earlier on.
