Brogrammers rarely exist in real life and like much satire it is easily misunderstood by those who are not in on the joke.
Jack: *takes off Northface backpack and removes iPhone earbuds--Ants Marchin audibly playing* "Yea, lemme just get settled first."

Courtney: "Sounds good, cya then ;)"
Milton: "Dad-Gummit Jordan, you're such a brogrammer."
Jordan: "Chill dude your day will come."
