Someone who is obnoxiously obsessed with marijuana. You will normally find these people looking fresh to death with their knee high marijuana leaf socks and Supreme wear. They let you know they are 420 friendly and make vegans look like saints. Some Whoabros spend their rent money on dab rigs and think it's cool to be a stoner by pretending to do a 3 gram dab and posting it on social media (most likely Tumblr or Instagram). Some may quickly become internet famous and then realize they can't keep making marijuana videos so they begin to make rap music or cringe worthy videos for their whoabro following. Whoabros are the weeaboo of marijuana and can be but not always closely related to the wook.
