The closest word I can think of is a sycophant but that’s too strong word and not exactly what I’m looking for. The word I’m thinking of has negative connotations and it’s for someone who is friends with different groups but only at a superficial level and isn’t necessarily honest about who all they’re friends with. This person would be seen as untrustworthy.
Sounds like this but not necessarily friends with lots of people: https://dictionary.cambridge.org/dictionary/english/duplicitous
I know of some who flit between groups, they are dangerous at times.
i learned a new word, thank you!
