Overused internet saying, started by the Clock Crew. It's meant to be a substitute for LOL, because Dwarfinator got banned for saying LOL on the NG boards. Taken from a costume company in the Halloween movies.
Silver Shamrock, that's awesome!

Fictitious mask company in the third instalment in the Hallowe'en franchise, "Season of the Witch" (the one without Mr. Myers). The masks are the colours of the Irish national flag (orange Jack-O-Lantern, white skull, green witch), and are made by a company in a weird all-Oirish town on the coast of California. On activation by a signal on the big night, the masks transform their (numerous) wearers' heads into so many divers creepy-crawlies. The Silver Shamrock company wins the booby prize for the most irritating television jingle ever inflicted on the world in fact or fiction; a countdown to the tune of "London Bridge is Falling Down", starting "(x) days to Hallowe'en, Hallowe'en, Hallowe'en". I had it in my head for WEEKS. The head of the company is played by an actor from Wexford, Ireland, and incidentally as far as I can tell is the only figure in the history of American horror films to pronounce Samhain correctly.
Four days left to Hallowe'en,
Hallowe'en, Hallowe'en,
Four more days to Hallowe'en,
Silver Shamrock!
