The Coolest Underwear On Earth A little kooky? Certainly. A tad unexpected? You better believe it! UNDZ considers itself “the coolest underwear on Earth,” and a glance at the goods confirms why: These boxer-briefs are emblazoned with some truly bonkers prints, including Pop Tarts, poutine (yurp), pink kitty cats, macaroni and cheese, and some very naughty cuss words that we won’t mention here because our mouths will get washed out with soap and soap tastes disgusting. These boxer-briefs, on the other hand, are absolutely DIVINE. Go grab ‘em.
