Many people like using pi tapes to measure the pipe size. Pi tapes, which wrap around the pipe the same way but have units in diameter, can be expensive. With calculators everywhere today, dividing by 3.14 is a snap, making these pi tapes not even necessary.
Fuck is an obscene English-language word, which refers to the act of sexual intercourse and is also commonly used as an intensifier or to denote disdain. Its origin is obscure but is usually considered to be first attested to around 1475, although it may be considerably older.
The phrase Fuck you, you fucking fuck! is a memorable quote from the movie Blue Velvet from 1986. Because of its vulgar status, the word fuck is usually restricted in mass media and barred from titles in the United States.
