I don't know ... I hug, kiss, and slap asses of everyone. I move people aside with my hands on their waist, pass out free back rubs .... whatever. It's all part of the master plan. It makes people uncomfortable sometimes, but it makes it known that I do what I want, when I want, how I want. Besides, empty affection is an awesome psychological tool. It's a very good benchmark to how much they're eating outta my hand as well. And yes I'm a walking HR train wreck at work, but after almost 5 years at this job I still have yet to have a single person (male or female) complain to management or HR. I'm just that good.
Now REAL affection defaults back to my original answer, but if we're just talking about touchy feely mushy stuff I dole that out like a $2 hooker.
