Klingon divorce
A Klingon divorce was the ceremony which dissolved a Klingon marriage.

The ceremony was much less elaborate than a Klingon wedding, and much shorter than a Human divorce. The spouse seeking divorce backhanded their partner, looked at him or her and said, "N'Gos tlhogh cha!" (Our marriage is done!). The spouse finished it by spitting on his or her partner. 

In 2371, Grilka performed this ceremony to divorce Quark at the latter's request. ()
