lable reserved only for those who are the top 1% in terms of both frequency of sex and number of sexual partners. It isn’t enough that they get laid more than one would expect. No. The person must be getting laid in amounts

unassuming or apparently beta. It’s not enough that the person gets laid a lot. They have to get laid a lot and equally appear to be the exact opposite of someone who ever gets laid.
