"Cheesus christ" was the name given by a couple to a Cheetos snack they found to resemble "Jesus Christ". The full excerpt from wikipedia is as follows :
"Cheetos have been the subject of public and media attention on multiple occasions due to the unpredictable shapes that form during the manufacturing process. Cheetos have been found in shapes which resembled the appearance of popular or historical figures. A single Cheeto described as being in the shape of Michael Jackson doing the Moonwalk Dance sold for $35.18 on eBay in the summer of 2009, attracting national media coverage in the U.S. A couple who found a Cheetos snack in a shape they described as resembling Jesus Christ nicknamed it "Cheesus" and garnered media attention as a result of their consideration of selling on eBay"
Such a thing does not exist in official english. Also, in my opinion, you should remove this word from your frequently used vocabulary lest someone takes it as offensive :D
