Played with both boys and girls, when you are "it", to tag someone you come up behind them and give him/her a swift slap right on the bum cheek, or you can slap both cheeks, if it pleases you to do so.
Dood, we got a whole gang togther and went out in a field and played a nice, friendly game of ass tag!!

The accepted standard that the tagged side of a towel is for designated nether-regions while the non-tagged side is reserved for the face and hair. This convention is used to avoid cross-contamination and is to be assumed as general practice. Practical in situations where one must use a borrowed or foreign towel.
"I forgot my towel in the shower and had to use my roommates. Hopefully he observes the ass-tag convention."

When you don't need to see someone's face in order to tell who they are so you look at their ass to check.
Friend: Hey who's that person right there?
You: I think that's Rachel.
Friend: How'd you know?
You: That's her ass bro. I was ass tagging.
