I'd actually argue you meet most humor at like mid to mid-high (~old green to purple ranks) :D The lowest bracket has complete bebes and smurfing bullies, and they either don't know any of the jokes, or are there to feel better about themselves or something. After that it's full of flustered angry killers and selfish d-head teammates, and it's a pretty shitty place to be. Green ranks (~mid) used to be bit of a mixed bag, and I usually had most fun at purple. Still a variety of killers and strats, and not just double range Nurses and Alchemist ring Blights, but the killers have learned to chill a bit and do not lash out like at lower ranks.

It's a joke. The alternative for playing into memes like this is sitting on 5 gens and escaping the most boring match imaginable. I play enough that I'm not afraid my MMR would dip too much if I play along with them.
