Ben Affleck Has Snug Shorts

Ben Affleck has a party in his pants while catching some waves with BFF Matt Damon on Tuesday.

The childhood pals practiced their surfing skills on shore before heading out to the water.

Ben, 34, and Matt, 36, have been in Hawaii with their families this past week on a week-long getaway. They’ve been picnic-ing, surfing, paddle boarding, and wading in the water with their daughters.
