A weebtard is a weeaboo (White person obsessed with japanese culture and anime) who is also retarded. One may argue that all weeaboos are retarded; suggesting all weeaboos are then weebtards. That would be correct.
I called the 40 year old virgin a weebtard and he then pulled a katana on me.
Pajama casual is a term used when working from home and preparing for a video conference. All business above the waist and your pajama pants down below.
We have a Zoom meeting in a few minutes and I’ll probably go pajama casual.
