What does rb mean?

The network term RB comes from the Sichuan-Tibet line, which is actually the abbreviation of Reb bull, which means red bull. The Sichuan-Tibet line is used to indicate that a person's physical exertion is very serious and needs help.

On the Sichuan-Tibet line, many backpackers will hold the sign of "seeking RB", which also means that this person's physical strength has been seriously overdrawn and needs some energy and help from others. Of course, the first person holding a sign will naturally follow this trend, so the slogan "RB" is defined.

1, thumbs up. On the Sichuan-Tibet line, you can always see many poor tourists giving thumbs up frequently on the roadside. This kind of hand gesture, in which the right hand is extended and the thumb is raised, and the other fingers are clenched, is also a common international lifting gesture. On the Sichuan-Tibet line, people often send a lift request to passing vehicles by posing this gesture, which is not a special signal.

2. A sign that says "looking for an asshole". Because sometimes the weather on the Sichuan-Tibet line is bad, especially at night, the risk factor will be even greater. Therefore, many poor tourists who go to the Sichuan-Tibet line alone will attract everyone's attention through the sign that says "Please fuck your mother", hoping to find someone who can live in a tent together. In this way, there is also a concern for each other.
