A Punk ass Bitch who will not stop talking. She will give you "55 minutes to work in class" but will talk for 45 of those minutes. She will threaten to take your phone, but when she catches you with it, she is too scared to take it. She has the ability make her entire class awkward in a matter of seconds. All in all, she looks like a crackhead, has a horrible sense in fashion, and doesn't teach.
You're being such a Mrs. Duncan right now, stop talking!

Get the mrs. duncan mug.
Mr Duncan is the type of person to be so insecure about his looks that he believes there is no point in being nice to girls
His jealousy of people that are not ugly and have the confidence to talk to girls spikes his anger therfore he calls them a 'white knight' as a way of making himslef feel better about not standing a chance with girls
A Mr Duncan will commonly have sheep that follow his way of living life
''That guy just called me a white knight, he is such a Mr Duncan. His sheep Dovydas and Zidane agreed with him''
