What does 'LPT' stand for?

“LPT” stands for “Life Pro Tip.” It introduces a practical suggestion intended to make an everyday task easier, cheaper, safer, or more efficient.

The abbreviation became strongly associated with Reddit’s r/LifeProTips community, where users share advice in a compact, recognizable format. A typical post begins with “LPT:” followed by the recommendation, such as a household shortcut, travel suggestion, or financial habit. The expression is now also common on social networks, forums, and messaging platforms.

“Pro” here does not mean that the advice comes from a licensed professional. It is informal wording suggesting that the tip is especially useful or clever. LPT is also distinct from “life hack,” although the two often overlap: a life hack is usually a technique or shortcut, while an LPT can be broader advice about decisions, habits, or behavior. In other contexts, LPT may refer to technical terms such as “line printer,” so the surrounding conversation determines the meaning.
