These people don't have any rhythm in their entire body and it's a shame because they're really starting to stick out from the crowd with their stiff limbs and awkward sexy faces. The whole point in dancing in clubs is to let loose and get rid of your stress from the week before. However, it's also used as a sort of mating call, you just see who is good looking, who isn't dancing like a tree and then you sort of go for that person. But you never talk to them until you've accidentally on purpose bumped into them and grinded on their leg because, romance.
