Macetein
A guy who’s so obsessed with his own junk, he thinks it’s the only thing that matters. He’s like a flower in a vase, but the flower is also the vase.
My neighbor is a macetein. He jerks off while eating breakfast, lunch, and dinner.
That guy is a macetein. He jerks off in the middle of a meeting.
My brother is a macetein. He jerks off while doing his taxes.
