A T-Poser is someone who does a T-Pose (the act of positioning your body into the shape of the letter "T" by standing straight up and extending your arms out from the sides of your body). This living meme refers to the reference pose used in 3D animation, but has evolved into asserting dominance on people, and even the creation of T-Pose cults in recent years.
