Brizzy is the combination of being named an white-Caucasian girl name "Brittany", while also being deeply in love and/or obsessed with Drizzy Drake.
Brizzy is one badass crazy white hoe who pounds hard and knows how to role with the dark meat boys. She has to fit both having the name "Brittany" while knowing every lyric to every Drake song.
A smooth talking badbitch.
"Hey Dante, did you see that bitch going wild singing at Drake's concert last night"
"yeaaahhh...she was definitely a Brizzy, that crazyass hoe"
