A microaggression is a slight against a person, intentionally or otherwise, that demeans a person's humanity and dignity. Microaggressions more often than not causes the recipient of the aggression to feel out of place or umwelcome.
While the term microaggressions has been a part of academic discourse for some time (micro-inequities was coined by an MIT Ph.D. in 1973), it became better known through the popular Tumblr Microaggressions. The Tumblr is a project that aims to highlight the daily microaggressions people encounter through user submitted stories.
