A person who literally can't
shut the fuck up. Like, geez guy, take a breath. Also he will
interrupt you to say something, probably something you were going to say, or to try and
contradict your point before you finish it
Guy 1: Hey so the other day I went to the mall to buy...
Manwell: You're joking, you went to the mall?
Everything is cheaper online. Why would you go to the mall?
Guy 1: ...something from the store my friend just opened.
Manwell: How was I supposed to know that?
Guy 2: Maybe if you weren't such a Manwell and you didn't interrupt us
all the time you would know.
