Another vote for boxer-briefs here. Truly, the best of both worlds.
Boxers are too loose fitting, and frequently ride up into The Phantom Zone, thus causing you to have to do that embarrassing reverse Picard Maneuver to unwedge them.
Briefs make Fandral, Hogun, and Volstagg (The Warriors Three) feel like they're stuck in the Death Star trash compactor, complete with the freaky one-eyed monster struggling to get out before the walls crush him.
We need to secure our borders, but also, we need breathing room!
