Clearly he’s accusing you of being someone else’s sock. I’d have said I definitely didn’t think so until you responded with a) a failure to understand the accusation, and b) a misspelling of the other poster’s initials. Both are well known amateur tactics used to deflect suspicion.
I hope you aren’t a sock. I was kinda warming up to you. But now I’ll be wary.
Use black marker to write unflattering and yet undeniably recent and pertinent message directed towards a poster or internet community on construction paper,
Photograph self holding same, usually with middle finger(s) displayed Johnny Cash style, and then
Upload and link photo to said community.
Personally I don’t care if you are a sock, your posts rock.
