Cross-Validation

Cross-Validation (CV) - Model validation technique used to evaluate how good a predictive model will perform in practice. It splits data multiple times in different places so the predictive model doesn't guide exclusively on one piece of data and decreasing the risk of overfitting making the model more reliable.

Is your model giving good results?
Yes, ever since I implemented cross-validation.

cross-vagination

Having sex with the person you're in a relationship with, and then having sex with your side piece. Later bringing it full circle back to your original partner with the possibility of transmitting an STD.

I banged my wife yesterday. Today, I banged my side piece, and then had to bang my wife again, thereby causing cross-vagination.
