The Jinsul equivalent of 'Your Momma' jokes

[Hmm]

I am running a PBP where we are starting our seventh round of fighting jinsuls. It's been a long and nasty fight, and also a bit of a slog because the party currently lacks a dedicated melee damage dealer. But this party of skill monkeys all speak jinsul, and thus have been trading insults with the jinsuls all the way through.

The jinsuls have been responding with insults of their own.

For example, when one of the party members called them ugly, the jinsul responded, "You're so ugly... you're flankable!" Which all the other Jinsuls in the room thought was hilarious. The party found it funny too, since the operative in question turned out to not actually be flankable.

But even I am starting to run out of good material, and it may be several rounds more before my party wraps this monster of a fight up.

So I would love your suggestions. It's okay if some of them make little sense. I expect Jinsul humor to get lost in context.

Thin skinned enough that you can penetrate their chitin with a harsh word?
Cried out of all their (many) eyes when getting a personal upgrade installed?

Going by the brief write-up on AoN about the species.

Your fighting style is so rigid you have an internal skeleton

[Kishmo]

"Yo' Progenitor so fat, Grand Herald Dhurus impaled heretics on their outer hull!"

"Yo' Progenitor so ugly, Kadrical let them leave the system!"

[BigNorseWolf]

"So stupid you can't find the floor with your tentacles

"so blind you can't see the human behind you in the dark

"So forward looking you can't see anything above you

"So stupid you cleaned with your legblade

[John Mangrum]

"You're only alive because your spawn-mates thought you too small to eat."

I'm currently playing Attack of the Swarm, and we thought it would be humorous if we changed things up and all played bug PCs.

We have a Trox, a Formian, a Kiirinta and a Xenomech Shirren.

We are the "Exoguardians", we make "Endo" puns all the time, and we use THIS as our group chat image.

"So dumb, you thought exocortex was shell oil."

"So ugly, they thought they'd salvaged trash when they found you."

"So fat, people thought you a space station."

"So skinny, they could use you as a legblade"

These all seem in the category of Bad Dad rips rather than actual smack, do they have weight? They'd appear to carry the right 'lost-in-translation' vibe the OP is looking for?

[Hmm]

I loved all of these, but the only one I wound up using (sort of) was one of BNW's. One of the shirrens in the group complained that the jinsuls were rigid in their thinking.

Inspired by the Wolf, I had one of the jinsuls respond to the shirren, "Rigid? Ha! You're so soft you're starting to grow an endoskeleton!"

Basically, the group -- finally -- got some crits and were able to finish the fight and the scenario. Yay!

Thank you all for inspiration and humor. This was great, and I hope you keep going, and this can be resource for other GMs looking for Jinsul insults.
