What does this mean (crochet pattern): Hdc in next 2 sts tog?

One half double crochet in the next two stitches together. You should really look up a guide for crochet acronyms / short form. Have that with you when you're working a pattern so you know what it means. Make your yarn over for half double crochet, put your hook in the next stitch and in the stitch after that, then complete the half double crochet. It's a way of decreasing, making something smaller.

You decrease I st by working 1 hdc over the next 2 sts.
