Bumptious: self-assertive or proud to an irritating degree. As in, “Claire’s not just confident, she’s downright bumptious.”
I imagine Claire Underwood gets up in the morning and on her vanity there’s a framed card that says “Bumptious Biznatch.” Right? I haven’t started watching season three yet, but somehow I imagine her thirst for power hasn’t been quenched. Maybe she’ll step over Frank and take the presidency...Now that would be some good TV.
