Yea. The guy liner thing has been going on for some 3ish years or more.
I have to admit, I don't know if I ever noticed a guy wearing guy liner outside of a guy already wearing a theatrical outfit to go along with the makeup.
Maybe that's why I don't notice it. An average guy isn't going to wear jeans, tshirt, sneakers, and guy liner.
I'm probably not that attentive, though.
