I am trying to find a term/word for the phrase "If you do not go, I will not go" in the context of trying to put pressures on others to attend events. I have begun to hear this heavily as we approach Christmas and am curious, is this technically a related form of Extortion? I am not sure what is a good place to ask this, so apologies in advance if this doesn't belong here, but I am looking for a dictionary term/word that describes this.
Wikipedia's definition of Extortion is "...a criminal offense of obtaining money, property, or services from an individual or institution, through coercion." Technically attendance could be seen as a service, and it could be coercion if you feel pressured to do something for fear of social rejection, but I don't think this is a criminal offense and seems too negative a term to explain it.
Am I stretching here? FYI not looking for legal advice or anything, just curious from a language stand point for sake of arguments with friends, etc. I imagine there is probably a far better, less negative/illegal term for this.
