A smirkative person is someone who smirks – a lot.
Yeah, I think that describes me. You are more likely to get a smirk from me than a smile at times. Yeah, and I do it out of smugness. I also do it when I’m amused by something that others would not find amusing. It could be the way something sounded (usually dirtier than intended) or when something makes someone sound idiotic…..or when I turn the tables on someone and maybe they haven’t realized it at the time.
My smirk just means something is going through my head that you may, or may not, want to know. Depends on the situation.
