Big Sean or Drake Created The #Hashtag Flow
The late '00s was the golden age of #Hashtag raps, a period when a series of rookie rappers picked up on the latest rap gimmick: simile raps that removed the "like" or "as" to build up anticipation for the one-word punchline.
There was Drake, whose verse on "Forever" nabbed the stylistic affect ("If I was at the club you know I balled...CHEMO"). There was basically every verse ("Soccer team!") on Young Money's "BedRock" (in particular, Gudda Gudda's infamous "I got her ... GROCERY BAG"). And of course there was Big Sean's "Supa Dupa," which made that gimmick the central conceit of the song.
But despite claims to the contrary, neither Drake nor Sean was responsible for the flow's creation, even if they did help popularize it. There are the obvious precedents: Kanye West on 2007's "Barry Bonds," for example. And it's hard to deny that Cam'ron was doing this even earlier, as in the opening lines to his verse on "Dipset Anthem" ("Make me put my two arms up...TOUCHDOWN.") But as Ludacris pointed out in his old-man-yells-at-cloud moment "History Lesson," the technique has even earlier roots. On "Buggin' Out" by Tribe Called Quest, Q-Tip beat everyone to the well: "Zulu Nation, brothers' last creation/Minds get flooded...EJACULATION."
