What does it mean when a guy gives a crotch display? Is this a sign he likes me?

I went to see one of my guy friends at work ( I like him, and I'm pretty sure he likes me( he's given all the classic signs)). He was standing behind the counter making normal conversation about what we did with each others weekends. Then out of nowhere he got really quiet and the vibe between us got a little different. He took a step back. His feet were shoulder width apart, he put his arms behind his back, puffed out his chest, and displayed his crotch to me. I, of course, couldn't help but stare for a few seconds then forced myself to look up to his face. He was staring straight ahead looking very confident. After I looked away and looked back at him, he returned to normal stance and started a new conversation. Was this a subconscious thing, or did he do this on purpose? What does it mean?

what? ha ha if that the only time you ahve seen him do it he might be trying to hint something but other than that I wouldn't give it too much meaning.

Thats weird, maybe it was his primitive way to show he wants to get in your pants?
