A 'Blair White' is a black and white wild cat you tend to see roaming city streets covered in their own vomit and urine. Also, a woman who thinks she is better than onision but isn't. She's just another white girl on YouTubetrying to make money off her 'fans'. She also doesn't have any clue what she is talking about, and likes to attack other YouTubers trying to feed of of them and gain popularity.
Damn it, there's another Blaire White on YouTube.

Blair White got put in her place by Onision.

Absolute motherfucking bad-ass anti-feminist who is willing to attack all movements that she feels is worthy of shit talking. Complete and utterly based. MUCH better than Onision ((:

Transgender, Anit-feminist YouTuber who actually has some common sense, is funny, and isn't afraid to speak her mind about transtrenders, feminists, sjws, Black Lives Matter, Islam, and Liberals. She's also fucking hot.
SJW: *Get's mad about Blaire White not caring about race*
Blaire White: Funny how that works.

A transgender (MtF) Youtuber whose videos touch on social topics such as, but are not limited to: pointing out flaws in modern western feminism, racism, transgender issues, social justice, the activist group Black Lives Matter, and debating select Youtubers (who are generally social justice warriors). In her own words on her channel's description, she "creates videos making fun of ideologues and cultural marxism". At the time of writing this definition, she is quite close to 250,000 subscribers. (She has 249,092 to be exact.) Most misrepresentative definitions of her are from the fans of another controversial Youtuber she had made a video on, Onision.
Blaire White is a Youtuber. She is starting to become popular within Youtube's 'intellectual/logic' community.

Having similar connotations to the phrase Uncle Tom, but specifically for trans folk. A Blaire White is a trans person, usually truscum, conservative or some thick, viscous mixture of the two who cannot stand the idea of nonbinary and GNC trans folk being seen equally as valid as them, and actively works towards the invalidation and erasure of the aforementioned groups in an effort to be seen as "more valid" by a group who only views them as a token tran who agrees with their reductive, regressive and hateful worldview.
