H'nemthe mating ritual
From Wookieepedia, the Star Wars wiki.
The H'nemthe mating ritual was a gruesome act in which the female would gut the male following sexual intercourse with their razor tongues, thought to have been driven biologically by the fact that male outnumbered female H'nemthe twenty-to-one. Other races looked upon this as barbaric, though male H'nemthe thought it would be worth it.
Feltipern Trevagg was killed by M'iiyoom Onith during a mating ritual.
