Insulting a Merfolk (skull and shackles)

[Beardsmith]

I am currently running a skull and shackles game and one of my players (a merfolk Barbarian) has tried having a insult battle with Rosie Cusswell.

I am terrible at coming up with insults on the spot. Anyone able to help me think of some good zingers to help put the scaly bastard in his place?

Remember these are coming from Rosie so they are probably vulgar (you dont have to go crazy with it though)

"Cross me again and you'll sleep with the fishes. Wait, you already do. I'll fillet ya, then."
"Whats that stench of my grannies privates? oh, its you tuna-legs"

[chaoseffect]

"I saw a bloated beached whale with a blow hole stretched out enough to sail a galleon through. Your mother by any chance?"

[Lipto the Shiv]

"You know, when people call you 'chum', they aren't being friendly."

"Whatever, roe for brains"

"You'd be better looking if your halves were reversed."

"Someone better get Fishguts[the cook], the dinner thinks it's a person again."

[Vamptastic]

"Hey look, it's the Little Durrmaid!"

[Cyrad]

"What's the matter? Got a hook in your lips?"

"Was your father a skum? That explains your awful stench."

"I'd rather sink my own ship than reel in a catch like you."

"Are you one of those fish where the female gets the male pregnant?"

"I should stuff you and mount you on my wall. That'll scare my ex-wife away!"

"I caught boots that looked prettier than you."

Tell him the jerk store called, and they're running out of him.

[Vamptastic]

"I got yer bait and tackle right here, sweetheart." Then grab your groin and pelvic thrust. Or, just shoot him in the face.

Gunslinger hooooo!

Work in insults based on how he doesn't have human body parts below the torso.
