蹭蹭 refers to a group of people who enjoy some convenience by sharing other people's resources. We call this kind of people "蹭蹭族". Nowadays, there are "蹭蹭族" in cities who enjoy "蹭". In their minds, "吃他人的口柔" has become an outdated concept. From food to daily necessities, they can skillfully use "蹭主义" to the extreme.

蹭蹭族 emerged with various integrity protection measures for online shopping. E-commerce websites have introduced various preferential measures for unconditional returns and exchanges to protect the rights and interests of buyers and thus promote transaction volume.

In this context, some buyers take advantage of the "unconditional return" clauses of online stores to get new products and famous brands and then ask for a return. Nowadays, "蹭蹭族" has become a common phenomenon.

蹭 has become a fashionable word among young people. "蹭" means eating, drinking, using the Internet, using computers, reading books, and using clothes. Now the meaning of "蹭" has evolved into enjoying some convenience by sharing other people's resources.
