Pop or POP is an acronym standing for "people of penises." This is a term for anyone who has a penis, and is made to be less gender based. This term includes cisgender men, some intersex individuals, some non-binary and anonbinary individuals, transgender men who have had sex reassignment surgery, transine women, many transsex/altergender women, and possibly pre-transitioning trans women.
This term is made to combat the ideology that having a penis is what makes one a man, and is made promote gender-neutral language and terms. This term can also stand for "person of (a) penis" if one wishes to refer to another person or themself as a pop.
