A semi-exclusive emotional and sexual relationship between two ex-partners. 'Semi-exclusiveness' refers to a state where neither splat partner is morally obligated to be faithful but must inform the other partner of any sexual or romantic contact outside of the splat.
Jimmy and Suzy broke up a few months ago but I've been seeing his car at her house a lot so I guess they are in a splat.
