#4. Waka Flocka Flame f/ Diddy, Rick Ross & Gucci Mane "O Let's Do It (Remix)"
Waka Flocka's wonky underground hit bubbled for more than a year before reaching critical mass in early 2010, heavily assisted by this knockout all-star remix. It's rare that you can actually say Puffy rapped his ass off, but here his verse is filled with "Arab Money"-level quotables ("I don't fuck with fake hoes/All I touch is J-Los!"). Backed up by an uncharacteristically funny verse from Ross (the genesis of his "I think I'm..." fantasy from "B.M.F") and topped off by a then-incarcerated Gucci (II), this is the dumb-out posse cut of the year.
