A man who unfoundedly glorifies himself and mainly his own (usually
small or disfunctional) penis and believes himself to be a
stud to the point where he thinks all women want his penis and he feels entitled to
sexual intercourse.
Also: willywardy willywarding
"The guy has like nothing going for him and he still wouldn't accept that I didn't want to have sex with him, he's a total willywarder."
"I
literally told the guy straight up how bad it was but he was
too much of a willywarder to hear it, he still thinks he rocked my
world!"
