What does the network term social cattle miscellaneous disease mean?

Social cattle disease refers to a person who is polite, shy and quiet when going out, arrogant and "crazy" when he is with friends, and so on. ? For example, I am shivering, passive to Nuo Nuo, shy, quiet and afraid to speak. What I often say is: um, I'm sorry, thank you and welcome. When I am with my good friends, I show my social arrogance incisively and vividly, and I am very arrogant. I often say, "What are you looking at?" And "Are you sick?" "Looking for a fight?" , "roll" and so on.

The specific performance is as follows:

Nuo Nuo is passive in front of strangers and punches in front of acquaintances. When I am alone, I dare not talk to others at all, and even see a group of people subconsciously detour. But when I am with friends, I don't care about the eyes of people around me at all, and I can do anything out of line in front of strangers. It seems that social bovine disease and social phobia are mixed together, referred to as social bovine miscellaneous disease.
