The number "143" is often used as a numerical code for the word "love." Each digit represents the number of letters in each word of the phrase: "I" has 1 letter, "love" has 4 letters, and "you" has 3 letters. This shorthand is commonly used in text messages and online communication to express affection in a simple and quick way. The use of "143" gained popularity in the 1990s, particularly among younger generations who embraced texting and digital communication. It is often associated with romantic relationships but can also be used among friends and family to convey warmth and care. The concept is similar to other numeric codes like "420" for cannabis culture or "911" for emergencies.
