Gruesomes
A 2-person team game that is more common as a betting game but is also sometimes used as a tournament format.
In Gruesomes, both members of the team tee off - and then the opposing team selects which drive they have to play. Needless to say, the opposing team is likely to select the worst - or most gruesome - of the two drives.

Following selection of the tee ball, the teams play out the hole in alternate shot fashion. The player who hit the "gruesome" tee ball also plays the second shot.
