Raunching is like dirty dancing and grinding in one. Usually involves kissing / members of the opposite sex but can occur amongst members of the same sex otherwise when too drunk to notice.
Haha, look Sarah is ranching with Alex. I think she had one to many vodkas tonight.

Look at that girl raunching him.. they should get a room as he has scored tonight.
