A non-binary person's vulva or vagina or other orifice used for penetrative sex, as opposed to cis and trans woman pussy (she/her) or trans man pussy (he/him). Different from bussy although it can arguably overlap.
It's hot gay summer, I hope I'll get some they/them pussy.
Used to describe someone who identifies as Nonbinary or someone who feels as if they do not belong in the pronoun groups of He/Him/His or She/Her/Her's
"My friend recently came out as Non-binary, luckily their parents accept them as who they are! So make sure to use They/Them/Their when you talk to them."
