Wilhelm, the name of someone who seems like a cool dude, they non-stop study. You presume, both of you hardly ever talk, matter of factly you hardly even know anything about the guy. You've never seen his face either, but none the less he still seems like a chill, possibly introverted person? Whom you could probably get on really well with, if you ever had a long lengthy convo.
"Woah. Wait. Wilhelm just popped up."
"That pretty chill dude?"
"Yeah that pretty chill dude."
