Answer:
the bandwagon fallacy
Step-by-step explanation:
Chris makes this argument to himself: "Everybody I know has at least one tattoo, most of my friends have three or four, but I have only one. So, it's about time that I get another tattoo." By making this argument Chris is actually engaging in the bandwagon fallacy
The bandwagon fallacy is simply thinking that everyone is doing the same thing so i must do it too, that it must be the right thing to do or joining everyone on the basis that you think everyone is doing it, and that there must be some truth about it which is what Chris thinks that because a few friends have tatoos let him join his friends believe that most of his friends have one or two and it is okay to get one.
