1)To be bad or horrible at snowboarding (or all extreme sports for that matter)
2)To say something very stupid
3)The act of swelling up like a mother fucker after being struck in the face
When Jimmy tried to pull a backside 540 with a method grab and landed on his face, causing him to swell profusly, hes fellow riders commented "DUDE! you just pulled the BIGGEST Pesar!!! You DUESH!!!!"
Get the Pesar mug.
