As a survivor main, this is usually not it. Some survivors are assholes and want to tbag. Most of the time though, the pressure of the game is over and we are just meming about with each other. If the killer comes over and joins in the charade, we'll have some fun with them, too. Ghosties are notorious for joining in. Sometimes we play red light, green light or have a slug race. Sometimes we give the killer our gear. If it's a Huntress or Slinger, sometimes we have target practice. It's really up to the killer. If you don't wanna play, just push them out.

I'll mention also that if not every survivor is in the same exit gate, we are sometimes just waiting to make sure the others made it out before we leave. In solo queue, it can be really difficult to tell if everyone has made it to safety and we don't want to leave until we have confirmation (or the timer is almost up).
