A more thorough explanation:

The front-foot rule is a principle used to determine how much improvement costs should be divided among several properties. According to this rule, the cost is divided based on the frontage of each property, without considering the benefits each property receives.

For example, if a road improvement project is being carried out in a neighborhood, the cost of the project will be divided among the properties based on the length of their frontage on the road, regardless of how much each property benefits from the project.

Front-running is a practice in the securities industry where a broker or analyst uses nonpublic information to buy securities or enter into options or futures contracts for their own benefit. This is done with the knowledge that when the information becomes public, the price of the securities will change in a predictable manner. This practice is illegal.

For example, a broker who works for a brokerage firm may buy shares in a company that the firm is about to recommend as a strong buy or in which the firm is planning to buy a large block of shares. This is done with the knowledge that the price of the shares will go up when the firm makes the recommendation or buys the shares, allowing the broker to make a profit.

Frottage is a sexual act where one person rubs their genitals against another person for sexual stimulation. This act can be done without removing clothing. When a child is involved, it is considered a form of sexual abuse.

For example, if an adult rubs their genitals against a child's body for sexual pleasure, it is considered frottage and is a form of sexual abuse.
