What does the girl mean by planting grass?

Girls say that planting grass means that girls strongly want to buy something, especially cosmetics and bags.

After being introduced by others, you have a good impression on something, want it or buy it. This is called planting grass.

Planting grass generally refers to the act of sharing the good quality of a recommended commodity to stimulate others' desire to buy. The antonym of planting grass is pulling weeds, which means pulling out the desire to buy or get something, that is, canceling the plan to buy or get it.

Planting grass has three meanings.

The first refers to the behavior of "sharing and recommending the good quality of a commodity to stimulate others' desire to buy", or the process of experiencing or owning something according to external information.

The second kind refers to the behavior of "sharing something and recommending it to another person so that another person likes it", which is similar to the usage of the network term "Amway".

The third is to describe something you really like from the bottom of your heart.
