• Tip: Gauge the audience. If you’re among veterans or history buffs, classic nicknames like “General Mattis” or “Mad Dog” are well-received. For a general audience, “Jim Mattis” is safe.
• Tip: Avoid over-familiarity. Nicknames like “Jimmy” or “Matty” should only be used if you have a close personal connection or are writing a very informal piece.
• Tip: When using a nickname online, check if it’s already taken as a username. Adding numbers or underscores can help, but unique combinations like “MadDogPhilosopher” work well.
