oncey 

The act of a female grabbing a guy's sex organ to check it for suitability before committing to further sexual acts. Not quite a handjob, but a possible precursor.

Kat wanted to go further with Steve, but when she got her hand down his pants for the oncey, she knew it had to end there.

Oncey 

derived from "once over." The act giving a hand job, but not really.

Dude I totally got a oncey from that chick. She was so drunk she couldn't finish.

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!"

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!
