Why do you use buses to describe women as indecent?

Bus is a kind of public transportation, but in the hot words on the Internet, "bus" has the meaning of mocking people, which means that a person lives carelessly and has relationships with many people. Some friends may find it strange, what is the relationship between buses and disorderly life? Let me explain below.

Origin: This word is caused by association. Taking the bus or getting on the bus is a phrase we use every day, and this "going on" and "sitting" will remind some people of some dirty things. Buses are crowded and relatively cheap public transport.

If people regard "getting on the bus" as a dirty word, they will naturally compare "bus" to that kind of casual person. With the spread, this stalk became popular on the Internet.

Synonym: public toilet.

Application:

As an adjective, it appropriately describes those people whose lifestyles are chaotic. For example, when talking about gossip, say, "XXX is a bus. It goes to the hotel seven times a week and brings a different man every time." Murder. You can take the bus to kill people when it is too noisy. I don't recommend this. After all, if this is groundless, it will also look vulgar. Personal feelings: Now many words have other meanings, and some make people blush, such as the bus in this stalk. I hope there are fewer such stalks, otherwise even daily communication will be affected, because some words are hard to say.
