I waited a while to backtext her because I didn’t want to seem too interested.

Backtexting 

Derivative of 'backstabbing', the act of being friendly to someone's face while secretly bashing them via text (usually while in their company).

I can't believe it, the whole time she was a guest in my house she was backtexting me to her friends.

vibe backtesting 

A casual approach to testing quant trading strategies using good-enough data, AI-generated code snippets, and gut feel for alpha. Less CFA rigor, more “let’s plug it into ChatGPT and see what 15-minute candles say.” Used early on to vibe-check ideas without investing in robust infrastructure or precise modeling.

Crypto Bro: “Yo I got this strategy that longs ETH whenever gas fees drop below median levels.”
Startup Quant: “Nice. You test it?”
Crypto Bro: “Yeah, did a little vibe backtesting on it — used some synthetic data and GPT to throw together a pandas loop. Looks promising.”
