Alt-right fuckboy

An alt-right fuckboy is an individual in the alt-right community (most noticable on the internet), who tends to act in an often hostile and irrational manner whenever a female alt-righter is either attacked or criticized online. This often leads to opposing opinions being either dismissed or silenced entirely.

Unlike the phrase "fuckboy", the word alt-right fuckboy is most of the time used as a slang to describe the nature of how someone on the alt-right might behave whenever a female alt-righter is confronted. In many cases, it may also be used as an insult.
