The act of eating corn on the cob whilst in a closet. People do this based on the common fear that eating corn on the cob in public is messing and embarrassing, especially when pieces of corn juice fly out of the corn and hit someone in the face. Therefore eating corn on the cob is best enjoyed when one is away from others, or in a closet.
"Man, I would eat this corn on the cob, but there are like all these hot chicks around. I might as well go closet cobbing!"
