My friend group’s inside joke is a TF2 reference and they have no idea

There was a kid at an overnight camp we went to who played tf2. We ordered McDonald's and he ordered a McFlurry. We all got our food, except for him. He screamed in his best Soldier impression "WHERE IS MY MCFLURRY YOU MAGGOTS?!" We have been repeating the line in the same voice over and over ever since. I am the only one who understands how cultured our group is.
