As defined by Wikipedia:
“Dominance and submission (also called D/s) is a set of behaviors, customs and rituals involving the giving by one individual to another individual of control over them in an erotic episode or as a lifestyle…
“It can be intensely physical, sometimes traversing into sadomasochism. In D/s, both parties take pleasure or erotic enjoyment from either dominating or being dominated.”
Here are some images of the classic Boot on Chest cocky pose. I suppose they are fun to look at because they depict “Dominance and submission” perhaps better than any other wrestling move.
