Twas the night before Christmas, when all through the house everyone was dancin' for no reason. Last night in Atlanta, 2 Chainz debuted a new ode to booty shaking while he handing out ribbon-wrapped bicycles. Today he shared the full song: a festive collaboration with Lil Wayne called, of course, "Twerk Season." A spirit has made itself apparent via ass shake, and Wayne -- like Drake before him -- wants to know who the fuck can focus with all this twerking going on? Rumor has it these two have some sort of joint project in the works? Happy holidays, indeed.
