The video below explains it more thoroughly — and includes amusing "IDK" shrugs from Seinfeld himself — but here is the straightforward version: Wale is making the jump from Seinfeld-inspired mixtapes to albums featuring actual Jerry Seinfeld. Says Jerry (live from the studio), "[Wale] wanted me to do something with him. I didn't understand it, but he did." And since Wale is apparently Jessica Seinfeld's favorite rapper, her husband said yes. "I do words." Not wrong, technically.
