On the Isle of Man, longtail is a euphemism used to denote a rat, as a relatively modern superstition has arisen that it is considered bad luck to mention this word. The origins of this superstition date to sea-taboos, where certain words and practices were not mentioned aboard ship, for fear of attracting bad luck (or bad weather).
The Manx Gaelic author Edward Faragher (also known by his Manx nickname 'Ned Beg Hom Ruy') recorded in his work 'Skeealyn 'sy Ghailck' that during his time working on fishing boats in the 19th century "It was forbidden to name a hare on board, or a rabbit, or a rat or a cat. The hare was 'the big-eared fellow', and the rabbit ‘pomet’, and the rat ‘sacote’, and the cat ‘scratcher'". In the modern superstition, the taboo only applies to the rat, and the term 'sacote' is no longer used.
Although this particular sea-taboo was one amongst many and was not held to apply on land, it has become a popular modern belief that the word is somehow unlucky and the taboo has been adopted by some as a typical Manx practice, despite the fact that the old Manx had no qualms in using the word, or its Manx equivalent, "roddan". In modern times, even non-local and unsuperstitious people will refrain from using the word "rat" perhaps in an effort to fit in with those who take it seriously, or in an attempt to be folksy.
Rats are various medium-sized, long-tailed rodents of the superfamily Muroidea. "True rats" are members of the genus Rattus, the most important of which to humans are the black rat, Rattus rattus, and the brown rat, Rattus norvegicus. Many members of other rodent genera and families are also referred to as rats, and share many characteristics with true rats.
Rats are typically distinguished from mice by their size. Generally, when someone discovers a large muroid rodent, its common name includes the term rat, while if it is smaller, the name includes the term mouse. The muroid family is broad and complex, and the common terms rat and mouse are not taxonomically specific. Scientifically, the terms are not confined to members of the Rattus and Mus genera, for example, the pack rat and cotton mouse.
The best-known rat species are the black rat (Rattus rattus) and the brown rat (Rattus norvegicus). The group is generally known as the Old World rats or true rats, and originated in Asia. Rats are bigger than most Old World mice, which are their relatives, but seldom weigh over 500 grams (1.1 lb) in the wild.
The Rat (子) is one of the 12-year cycle of animals which appear in the Chinese zodiac related to the Chinese calendar. The Year of the Rat is associated with the Earthly Branch symbol 子.
People born within these date ranges can be said to have been born in the "Year of the Rat", while also bearing the following elemental sign:
This is a partial list of characters in the comic strip Pearls Before Swine by Stephan Pastis.
Rat is a megalomaniacal, misanthropic rat, who is frequently critical of the strip's style and artwork, as well as the other characters in his and other strips, real life people, and almost all living (and often nonliving) things. He believes himself to be much more intelligent than he actually is, and thinks more or less anybody else is stupid with the only person he believes worthy of his respect being Leonardo da Vinci. He tends to irritate people, particularly his intelligent friend Goat, and is easily irritated by his naïve, dim-witted housemate Pig. Rat believes himself to be the wisdom of the strip, if not wisdom itself, and that anybody else is more or less dumb, whereas most other characters view him as "a loudmouth, pompous malcontent". He may or may not be a personification of the Seven Deadly Sins.
Rat is very prideful and arrogant (he once made a list of all the geniuses in the world that only said "Mozart, da Vinci, Me", and then said that he only put 'that music dude' there to be nice), and is constantly dreaming up schemes that invariably would keep him away from anyone and everyone else, though these inevitably backfire. He often appears incapable of seeing his own faults.
