A man who woke up at a party to find a penis had been drawn on his face was then killed by a DJ after "boy banter" got out of hand, the Old Bailey heard.
Anthony Thompson, 26, died after being punched by Thomas Evans, 32, outside a flat in Tooting, south London. Vanessa Barrows, who was hosting the party, said: "It was a joke. They were friends."
Mr Evans of Morden, Surrey, denies manslaughter. The trial continues.
