Once too often 

If you do something once too often it means that you have repeated an action which is bad, stupid or dangerous with an unpleasant end result. So you end up looking a complete wanker, in A & E with serious injuries or someone is totally pissed off with you to an extent which is going to be detrimental to your health and wellbeing.

He’s pissed them off once too often, they’re going to put the fucker on crutches.

Crazy? I was crazy once. 

A copypasta meme from early internet culture that was made famous by Youtuber Kryoz. The saying is able to go on a loop.

EX:

Crazy? I was crazy once. They locked me in a room. A rubber room. A rubber room with rats. And rats make me crazy. Crazy? I was crazy once-

"Crazy? I was crazy once.-" "Shut the Fuck up Gerald, we're trying to sleep!"

Onsen 

An onsen is a Japanese style public bath using volcanically heated hot water from the ground.

The term onsen is often used in the Japanese language in reference to the bathing facilities surrounding hot springs.

Onsen, when translated into English means 'hot spring', which can lead to confusion and miscommunication.

After watching the monkeys in the hot spring, do you want to go to an onsen?

Once you go metal you won't want to settle 

It's the future of sex. Sex with hot robots. They feel surprisingly soft, but can turn tough and durable during battle mode. It's based on smart metal. It's a metal that's already under development, but will be fully developed in the future. It's a metal that can change material properties at will(they could get soft, smooth and squishy like normal or wet human body tissue, but get tough like steel during dangerous situations and battling). Girl sex bots. Sex-bots.

Dude 1: I like Jenny XJ9.
Dude 2: Well. Once you go metal you won't want to settle!

I can't stop you from trying ... Once

A good answer to a violent threat, if you can back it up!

I see you fingering a weapon in your jacket, so go on ... I can't stop you from trying ... Once.
