Newfoundland Screech is used in a ceremony known as the "screech-in."  The "screech-in" is a ceremony performed on non-Newfoundlanders (known to Newfoundlanders as a "come from away" or "mainlander") involving a shot of screech, a short recitation, and the kissing of a cod.  It is often performed either in homes or in town pubs.

The general process of a screech-in varies from pub to pub and community to community, though it often begins with the leader of the ceremony introducing themselves and asking those present if they'd like to become a Newfoundlander.  The proper response is a hearty "Yes b'y!"  Each participant holding their shot of Screech, they are then asked, "Are ye a screecher?" or "Is you a Newfoundlander?," and are taught the proper response: "Indeed I is, me ol' cock!  And long may yer big jib draw!"  Translated, it means, "Yes I am, my old friend, and may your sails always catch wind." 

A codfish – or any other fish unsightly enough to suitably replace the cod – is then held up to the lip level of each participant, who then bestows the fish with a kiss.  Frozen fish is used most commonly in the screech-ins, though occasionally a fresher specimen, if available, will be used.  Most places will also award certificates to those who have become an honorary Newfie once the screech-in is complete. 

Some screech-in traditions vary in both the order of events as well as the requirements.  Some ceremonies require that the screech-ee eat a piece of "Newfie steak" (a slice of baloney) or kiss a stuffie puffin's rear end.  Some also wear the Sou'wester during the recitation and the drinking of the shot.  In all cases, only a native Newfoundlander can officiate a "proper" screech-in.
