Human cereal bowl
An act usually reserved for parties or the refreshments of an orgy. A man with a chest dent has his legs put behind his head and his arms wrapped around his buttocks. His dent is then filled with cereal and milk for the enjoyment of the party-goers or orgy participants.
Ted has the grossest chest dent! We should invite him to the next orgy party and make him into a human cereal bowl.
