Flake

A rather crazy performer. A flake's antics are more likely to elicit amusement than indignation, as far as most bystanders are concerned. The prime example of a flake was Frank Kovacs. Bobby Riggs during his ballyhoo career as senior player might be another. Some players like Ilie Nastase, Jimmy Connors, and John McEnroe have flaky characteristics, but they are less attractive than flakes.
