Guy 1: "Dude, this guy reloads too much!"
Guy 2: "Yeah, he has ERS"
is a gender-inclusive, third person singular pronoun, referring to a human person without gender reference. In other words; it adds to gender-referenced He/She (S/he), His/Her, His/Hers; and some times replaces them, to produce the pronouns that refers to a genderless (gender-neutral) third person singular.
He Ee She,
His, Er, Her
His, Ers, Hers
I, you, He, She, Ee, It
We, You, They
My, Your, His, Her, Er, Its
Our, Your, Their
Mine, Yours, His, Hers, Ers, Its
Ours, Yours, Theirs
It basically adds one more pronoun to the common English language pronoun-count table, changes it from 8 to 9.
This gender-neutral possessive and personal pronoun combination was originally invented by the American feminist National Organization for Women (NOW), in 1970’s; as a means to remove and replace the use of common gender-referenced personal pronouns (He, She …). Their argument was; the use of any gender referenced pronoun in the modern world of gender equality is completely unnecessary, since both genders are 100% equal.
But unfortunately, their view was not received warmly and was rejected by the masses. People thought that, in the pursuit of their quest for gender equality, they went overboard when they intended to erase and remove any gender related references from the English language. Evidently their efforts failed miserably, since no one has stopped using the gender-specific pronouns anywhere in the world, even after NOW devoted many years of lobbying and many millions of dollars of funds to this lost cause.
Nevertheless, there are many instances in-which any English writers might intend to refer to a third person singular without a gender reference; not because of the aims of NOW, but because what they are referring to, in their specific situation, is truly gender neutral. Prior to presence of; Ee, Er & Ers, we had no choice but to resort to; S/he, His/Her & His/Hers. Now we can simply use Ee, Er & Ers.
