None of the above, because “Dom” is not a verb. “Dom” isn’t something we do, it’s something we are. When I read something like “So I was with this guy last night and he Dommed me real good,” it’s like fingernails on a blackboard.
Here’s a little thought experiment, a couple of hypothetical constructs:
1. Said by a Dom: “So I was with this girl last night and she subbed me real good.”
2. Said by a gay person: “So I was with this guy last night and he gayed me real good.”
“Dom” is an attribute, not an action. An adjective. Example: “I am a Dominant male.” Submissive works the same: “I am a submissive female.”
