Nickname for Conan O'Brien, imparted by Tom Hanks on the former's second episode as the new host of The Tonight Show in 2009. The nickname combines Conan's self-bestowed nickname from earlier in the same show, "CoCo," and his middle name irl, "Christopher," also revealed earlier in the same show when Conan showed his new California driver's license.
Jim: Is that dude with the big ass chin still hosting The Tonight Show?

Hank: No way, man, CoCo Christopher took over hella days ago.
