Dry HuMpInG

Do you ever stop and think about what goes on in the club or college parties? As a freshman I was all for it but in my sophmore year i had a revelation. I went to one college party not feeling so good so naturally i just chilled out and sat outside the dance floor and just watched everybody dancing. I noticed a majority of the guys were behind the girls grinding on their backsides or in some cases just dry humpin. I just thought to myself has dancing in the club resulted to dry humping? Where is the art form of that? Do us guys really just dog girls out like this? Let me know what you think.
