Eating The Breadstick
When kids at school get so silly they slide across beams like they're trying to escape a teacher's wrath. It's the school version of being a total idiot.
My homie slid across the gym beam like he was trying to escape a math test.
I saw two girls slide across the hallway beam and one fell into a trash can.
That kid slid across the beam and got caught by the principal. He's dead meat.
