One who designs or acts in a way that obstructs others, making it difficult or
impossible to do what needs to be done. Frequently uses conflict of interest to obstruct others. Also known as an
asshole or
duh-weeb, and most likely proud of it.
When you have to drive six blocks just to go around the
corner, it's a good sign that the
engineer who planned the city's one-
way streets was an obstructionist.
