Right twist question

Silly question probably but… every instruction I have seen for making a right twist after the instructions on what to do to make the twist, it says, slip both sts off needle at once. Okay, does that mean to just drop them off the left needle or slip them to the right needle? I don’t know why I am having so much trouble wrapping this around my brain.

Just drop them off the left needle like you do when you’re done knitting into a st.

Thanks. I am not sure why I was having such a problem with this. Since practicing it I understand it better. One thing I know, I have always had a tight tension and know I have to learn to knit a bit looser, especially when trying one of these stitches. Something I have to work on that is for sure.
