This is a phenomenon that occurs during group chat, when someone asks for an opinion/question, and then right when you say, "i agree" someone before you says another opinion, so the other people dont know who you agree with...
Group Chat:

Megan- Hey guys, do you think we should have a constitution? I mean, we're trying to create a fake project, I think its worth it.

Jack- I dont think it's neccessary

Vishal- I agree

Jack- with who?
