He/she is a set of pronouns containing both the pronoun sets of she/her and he/him. It is used typically by people who identify as both masculine and feminine genders, but anyone who feels comfortable with them can use these pronouns if they fit you.
In some cases the person putting he first instead of she can indicate a preference for he, but this is not every case and can be the opposite or they can be equal.
Oh, Darell goes by he/she pronouns. It means he can be called she or he. Sometimes she prefers one over the other as well.
A person like myself that has both male and female genitals. At birth the doctors didn't know what i was so my parents chose a sex for me. I am now a male. I was born with both ovarian and testicular tissue. You can still see some male and female sexual characteristics though I take hormones.
A man who dates women with the sole purpose of exploiting their time, energy, and labor while he sucks the joy and happiness from their lives.
"That guy's a soul digger. He'll expect you to work full time, but you'll be doing all the cooking, cleaning, laundry, shopping, and childcare while he plays video games or watches TV."
A person pretending to be something they aren't, or an impostor. This is inferred because of the old alien movies where alien pods appear on earth and the "pod people" dispose of the humans and slowly reproduce the bodies, pretending to be humans.
The pod person was pretending to be my father, but I knew that he was an alien when he acted differently than my father ever would have.
