Translation of a slang for 'mutual flattering' circle jerk



(vulgar, slang) Any group or group activity indulging in excessive mutual praise.


When I try to translate this term in this context, I come up with 互相吹捧 and 互相奉承 (mutual flattering). It gets closer if I reduce 互相吹捧 to 互捧. But it doesn't contain any vulgarness or even derogatory sense like the English original does.
Question: Is there a counterpart in Chinese that matches this particular vulgar slang?
My impression is it is unlikely because excessively praising each other is not considered unseemly behavior in Chinese culture in general
Depending on the context and situation you can consider some of these:
自嗨
Douban

因为难以忍受这种circle-jerk话题的自嗨臭屁。


I originally wrote this as a joke but I think it's quite apt:
互相捧场，共同成长(cháng)
I won't explain it here though.
