jump-off
Where things begin
A jump-off is a starting point or place of departure, especially for a military operation or expedition: The base served as the jump-off for raids into enemy territory.
In equestrian sports, a jump-off is a tiebreaker round where riders compete over a shortened course against the clock.
In slang, a jump-off is a casual sexual partner—someone for hookups rather than a relationship.
