look up any word, like half chub:
Golf terminology meaning "to snatch defeat from the jaws of victory". In specific terms the Dymond refers to a situation when a golfer plays well on the front nine and then plays poorly on the back nine. For example, if a player was to be in the lead after nine holes and then fail to win after 18 holes then it would be said that he has done a " Dymond".
The terms "Dymond" and "doing a Dymond" originated in Australia although the actual spelling of the word stems from South Africa. It is unclear exactly when the term was first coined however it has seen a significant rise in usage and popularity since 2008.
President Obama started his term in Office really well, then he did a Dymond.
