Indiana ? Two Indiana men have declared Monday “National Man Day” only to find there’s already a romantic holiday that falls on that date.

Nineteen-year-old Joel Longanecker of Celestine and his 26-year-old brother Aaron, of Indianapolis, have for months been rallying thousands to their masculine cause on Facebook. More than 260,000 people have pledged to “stand up and do manly things” on Man Day.

But it turns out June 15 is also “Sneak a Kiss Day,” a day for sweethearts to steal smooches from their sweeties.

The Man Day organizers urge participants to take part in “manly” activities such as football, hunting or watching Rocky movies. They claim real men don’t “sneak” kisses.
