It was a jab at gender-whatevers who are sometimes incorrectly identified as another gender. "Did you just assume my blank" is a commonly used phrase when someone makes an assumption (even if sound), used for a humorous effect, since that is what the incorrectly identified individual will ask (with the "blank" being replaced with "gender").
Karma would the net sum of all positive and negative comment scores, and I jokingly implied that your assumption of karma being useless was actually wrong, and in this case I impressed chicks/got laid as a result of my karma (which is untrue).

I got the retard SJW bit but had no idea what the karma part was. Is that on this site or another one?
